469648
2x - 6y = 37\n-6y = -2x + 37\ny = (2/6)x - (37/6)\ny = (1/3)x - (37/6)

For the second equation, move the 9x to the left side and the -21 to the right side\n3y - 21 = 9x becomes\n-9x + 3y = 21\nRight the equations, so that one is right below the other one.\n3x - 2y = -8\n-9x + 3y = 21\nYou can cancel out the x's by multiplying the top equation by 3\n3(3x - 2y) = 3(-8) becomes\n9x - 6y = -24\nNow you have\n9x - 6y = -24\n-9x + 3y = 21\nAdd the two equations together\n-3y = -3\nThus, y = -1\nTo find x, replace y with -1 in either one of the original equations.\nYou will find that x = -2\nAnswer: (-2,-1)

First, you multiply the top equation by 2, to get:\n\n2x+2y = 8\n2x - y = 2\n\nThen, subtract the top equation with the bottom equation.  That is,\n(2x+2y) - (2x - y) = 8 - 2\n2x + 2y - 2x + y = 6\n3y = 6\ny = 2\n\nNow that you know the value of y, you can now solve for x, using any one of those two equations.  Let's use the second one.\n\n2x - y = 2\n2x - (2) = 2\n2x - 2 = 2\n2x = 4\nx = 2\n\nTherefore, x=2 and y=2 is the solution.

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

so easy. 9y-11=7. add the 11 to the 7 so 9y=18. Divide by 9 so y=2.  20+4m=42. same thing. subtract 20 so 4m=62. divide by 4 so m=15.5

y=-6\n4x+y=2\n\nsubstitute -6 for Y\n\n4x-6=2\nadd 6 to both sides\n\n4x=8\nDivide both sides by 4\n\n\nx=2\ny=-6 (taken from above)

8y=-23-x\n\n-5x+8y=19\n-5x+(-23-x)=19\n-6x-23=19\n-6x=42\nx=-7\n\n-7+8y=-23\n8y=-16\ny=-2\n\n\nThe solution is (-7,-2).  I've checked it, so it works.  However, it is a good idea to always check the solutions.  Since you end up using only one equation to find the second variable, make sure the pair also works in the second equation.\n\nHope this helps!

Solve for y in the first equation and then substitute into the second equation.\n4x + 2y = 0  Subtract 4x from each side\n2y = -4x  Divide both sides by 2\ny = -2x\nSubstitute -2x for y in the equation 6x + 3y = 0\n6x + 3(-2x) = 0\n6x - 6x = 0\n0 = 0\nThis means there are infinitely many solutions of the form (x,y) where x is any real number and y = -2x.\nTherefore, the answer is\n(x,-2x), where x is any real number.
