2x = 3x + 1; -x = 1; x = -1.
3x=2x-12x=-12
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line
3x - y = 3y = 2x + 2Put the value of y in the 1st equation:3x - y = 3 it will be -->3x - ( 2x + 2 ) = 33x - 2x - 2 = 3x - 2 = 3X = 5Put the value of X in the 2nd equation so as to find the value of Y :y = 2x + 2y = 2(5) + 2y = 10 + 2Y = 12
2x + 2 = 3x - 57 = x
2x = 3x + 1; -x = 1; x = -1.
2x+3x = 5x
3x=2x-12x=-12
3x - 3 = 2x + 6 3x = 2x + 9 x = 9
-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line

2x + 2 = 3x - 57 = x
3x - 12 = -2x + 235x = 35 so x = 7
3x
3x+5 = 2x+13 3x-2x = 13-5 x = 8
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x + 8 = 2x +28 3x - 2x = 28 - 8 x=20
