2x+3y=13 3x-y=3 x=2
2x+3x = 5x
3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3
3x + 2x = 40 5x = 40 x = 8
-3x + 2x = 6Let's abbreviate left part by cancellation:-x = 6The answer will be:x = -6
2x+3y=13 3x-y=3 x=2
3x+1+2x-2 = 64 3x+2x = 64-1+2 5x = 65 x = 13
2x+3x = 5x
3x - 7 = 5x + 13-2x = 20x = -10
3x+7=5x-13 ----> 3x-5x=-13-7 ----> -2x=-6 -----> x=3
x = 3 and y = 2
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
3x+56 = 2x+4 3x-2x = 4-56 x = -52
3x
3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
3x + 7 = 5x + 13 3x - 5x = 13 - 7 -2x = 6 -x = 3 x = -3
