3x+56 = 2x+4 3x-2x = 4-56 x = -52
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
3x+4 = 2x-3 3x-2x = -3-4 x = -7
2x+5=3x+1 -x=-4 x=4
3x - 2 = 2x + 4 3x - 2x = 4 + 2 x = 6
3x + 4 = 8 + 2xSubtract 4 from each side:3x = 4 + 2xSubtract 2x from each side:x = 4
-2x+20 = 3x 20 = 3x+2x 20 = 5x 4 = x So x = 4
3x + 2x = 5x. 5x= (-4) X = (-4)/5 x= -0.8
2x-4
2x+3=3x-3 2x-3x=-3-3 -x=-6 x=6
x = 4
-2x + 3x = -4 By combining like terms we get: x = -4.
