2x - y = 7...Equation A\n\nx + 4 = 8...Equation B\n\nWe can find x in Equation B by subtracting -4 from both sides.\n\nWe get this:  \n\nx = 8 - 4\n\nx = 4\n\nNext, plug 4 into Equation A to find the value of y.\n\n2(4) - y = 7\n\n8 - y = 7\n\n-y = 7-8\n\n-y = -1\n\nYou need to divide each side of the equation by -1 to find y.\n\nDoing this we get:\n\ny = -1/-1\n\ny = 1\n\nTo check if I am correct,\n\nplug your value for x and y into BOTH original equations to see if BOTH SIDES of BOTH equations are equal.\n\nGuido

Put Y=tan x and solve the equation for Y.\nThis gives two solutions Y=tan x = 1,7808 and Y =tan x = -0,2808.\nThis leads to x = 60.68 degrees and x = -15.68 degrees.\n\nAdd 360 degrees to the second solution and transform to degrees and minutes for the final answer.

Ah, systems.\n\nthe first problem- there are many ways you can choose to do this, but I think we should multiply both sides of the first equation by two so that they positive and negative y's will cancel out.\n\nSo now we have:\n2(2x + y)=2(4)\n3x - 2y = -1\n\nSimplified:\n4x + 2y = 8\n3x - 2y = -1\n\nnow you add down, so you get:\n7x +0y = 7\n7x =7\nx=1\n\nsubstitute 1 for x in any equation:\n2(1)+y = 4   \n2 + y = 4\ny = 2\n\n\n\nfor the second one- lets cancel out the y's again.\n\n5x - 3y = 14\n-3(2x - y) = (6)-3\n\n5x - 3y = 14\n-6x +3y = -18\n\nAdd them together:\n-x = -4\nx = 4\n\nThen solve for y:\n5x - 3y = 14\n5(4) - 3y = 14\n20 -3y = 14\n-3y = -6\ny = 2

you have to set up two equations....x+y=24 and .10x+.25y=3.00\n\nnow you can do to things...one way is to solve the first equation for x or y then    x=24-y.... sub this into x in the second equation    \n.10(24-y)+.25y=3.00\n2.4-.1y+.25y=3.00  combine terms\n2.4+.15y=3.00\nsubtract 2.4 from both sides\n.15y=.6 divide both sides by .15\ny=4  x=20

1) y=x+4\n   3x+y=16 (I guess you made a mistake by writing +16)\n--------------\nsubstitute x+4 for y in second equation and you'll get\n\n   3x+x+4=16\n    4x+4=16\n    4x=12\n     x=3\n\nnow y=x+4=3+4=7\n\nsolution (x,y)=(3,7)\n\n2) 4x+5y=48\n    y=3x+2\n--------------\nsubstitute 3x+2 for y in first eq.\n\n4x+5(3x+2)=48\n\n4x+15x+10=48\n\n19x=38\n\nx=2\n\nnow y=3x+2=3*2+2=6+2=8\n\nsolution (x,y)=\n(2,8)\n\n3)3x-y=0\ny=6\nin first equation instead of y write 6\n\n3x-6=0\n3x=6\nx=2\n\nso, the solution is (2,6)\n\n4) x-2y=-10\n3x-y=0\n\nfrom the first equation you have\nx=2y-10\nnow substitute 2y-10 for x in second one\n\n3(2y-10)-y=0\n6y-30-y=0\n\n5y=30\ny=6 \nnow x=2y-10=2*6-10=12-10=2\nso x=2 and y=6

Divide 840 by the answer from this equation (0.08 - 1), then you can solve for "y".\n\nGood luck!

Write the equation in the point-slope form, then substitute 0 for x and solve for y.  That is the y-intercept.
