simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
3x=2x-12x=-12
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
A Letter.14-2x=3x+113-2x=3x3=5xX=0.6
simplify it, 7x-12=x+2+2x-3x 7x=2+12+3x-3x 7x=14 x=2
3x=2x-12x=-12
5x+7=3x-21 -7= -7 5x=3x-14 -3x=-3x 2x=-14 2x/2x=2x/-14 x=-7 The Answer Is -7 -
2x+12-3x = 5 2x-3x = 5-12 -x = -7 x = 7
3x - 12 = -2x + 235x = 35 so x = 7
A Letter.14-2x=3x+113-2x=3x3=5xX=0.6
2x+12-3x = 5 2x-3x = 5-12 x = -7
2x-12
x+2x+14=5x+2 3x+14=5x+2 (add x's on same side)3x+12=5x (-2 from both side)12=2x (-3x from both sides)2x=12 (turn around for tidyness :P)x=6 (divide each side by 2 to get answer)
(3x + 2x) -12 =5x-12 the answer is 5x-12 it is just a simple case of simplifying
3x+7=2x-5 x=-12
3x+10=14+2x so subtract 2x from both sides x+10=14 so x=14-10 so x = 4
