2x + 4y = -6\nX - 3y = 7 multiply by two\n\n2x + 4y = -6\n2x - 6y = 14\n{subtract equation 2 from equation 1}\n\n2x - 2x + 4y - (-6y) = -6 - 14\n10 y = -20 divide by 10\ny = -2\n\n\nplug into a equation \n2x - 6(-2)  = 14\n2x + 12 = 14\n2x = 2\nx = 1\n\nx = 1, y = 2

You have two equasions 2x=3y and y=2x+4\nYou're going to plug one equasion into the other; plug the y= into the  first equasion because the y is already by itself.\n2x=3(2x+4) (I plugged what y equaled into the y in the first equasion.\nThen you solve for x\n2x=3(2x+4)\n2x=6x+12\n-4x=12\nx=-3\nNow that you have solved for x, plug x back into the y='s equasion\ny=2x+4\ny=2(-3)+4\ny=-6+4\ny=-2

first, solve for x or y\nSo, \n8=5x-(-2x+6)\n8=5x+2x-6\n8=7x-6\n2=x\n\nPlug that value back in\ny=-2(2)+6\ny=-4+6\ny=2\n\n(2,2)  graph the point

8Y(2Y-1)=0\n16Y^2-8Y=0\n16Y^2=8Y\n16Y^2/y=8Y/y\n16Y=8\nY=8/16 or 1/2

2x-4y = 3.8\n3x - y = 17.7\n\nmultiply second equation by -4 so that when u add them both u will cancel the y's...\n2x-4y = 3.8\n-12x+4y = -70.8\n\nnow add them..\n\n-10x = -67\n     x = 67/10 = 6.7\n\nnow plug this x in for any one of the original equations and solve for y....\n\n2(6.7) - 4y = 3.8\n\n13.4 - 4y = 3.8\n-4y = -9.6\n   y = -9.6/-4 = 2.4\n\nso the solution is (6.7,2.4)

1. y2+6y+8 = (y+4)(y+2)\n2. x2+7x+12 = (x+4)(x+3)\n3. z2+2z-24 = (z-4)(z+6)\n4. x2+7x+10 = (x+2)(x+5)

you would take the 2x-4y=3 and solve for a variable, such as x=(3-4y)/3   you now have what x equals and you sub that into the other equation so you now have 2[(3-4y)/3]-3y=0 and you should be able to solve that equation

The first thing that I would do is to get the equation into slope-intercept form:\n2x + 3y + 6 = 0 --- Subtract 6 from both sides...\n2x + 3y = -6 --- Subtract 2x from both sides...\n3y = -2x - 6 --- Divide both sides by 3...\ny = -(2/3)x - 2\n\nNow, since this equation is in the form y = mx + b; where m is the slope, we can easily see that the slope of this line is -(2/3).\n\nAnswer: (4) -2/3

4x-2y-6=0\n+6      +6\n4x-2y=6\n\ny-2x=-5\n*2   *2\n -4x+2y=-10\n+ 4x-2y=6 (adding the previous equation)\n  0+0=-4\n0=-4\nNo solution\n\nTo graph:\ny-2x=-5\n+2x  +2x\ny=2x-5\nGraph that\n\n4x-2y-6=0\n+6      +6\n4x-2y=6\n-4x  -4x\n-2y=-4x+6\n/-2   /-2\ny=2x-3\nAnd graph that. As you can see, the lines do not intersect, confirming the answer of no solution.

iso late the y by subtracting 6x from each side, so you are left with 2y = 9-6x, then divide each side by the coefficient of y (2) making your equation: y=9/2-3x...the y intercept of the line is 9/2 and the slope is -3 (so start at the point on the graph 9/2, then move 3 squares down, and over to the right one)

x*y=90\nx=2.5y\n\nSubstitute 2.5y in for x:\n(2.5y)*y=90\n2.5yy=90\n2.5/2.5 yy=90/2.5\nyy=36\ny^2=36\nSquareroot(y^2)=squareroot(36)\ny=36\n\nplug-in y:\nx*6=90\n(also known as 6x=90, as is normally written that way)\nx*6/6=90/6\nx=15\n\nThus, 6 and 15\n\ny=15

y = 0.5x-4 \n\nor similarly\n\nx= 2y +8

switch the y and x\n\nx = 2y - 3\n\nThen solve for y\n\nx + 3 = 2y\n\n(x+3)/2 = y\n\nnow you have the inverse.

Begin with where you left of:\n\n2x + 2yy' = 0\n\nDifferentiate again, just like the first time.  Use the chain rule on the yy' term:\n\n2 + 2(y'y' + yy'') = 0\n1 + y'^2 + yy'' = 0\ny'' = (-1-y'^2)/ y\n\nFrom your y' = -x/y\n\ny'' = (-1-(-x/y)^2)/ y = -x^2/y^3 - 1/y\n\nThis isn't the answer you have but see if they are the same:\n\nx^2 = 4 - y^2\n\ny'' = -(4-y^2)/y^3 - 1/y = -4/y^3 + 1/y - 1/y = -4/y^3\n\nSo the two solutions are the same
