7x-5x=8 2x=8 x=4
It is: 12x
142
7x + 12 = 5x + 2 Subtract '12' from both sides Hence 7x = 5x -10 Subtract '5x' from both sides. 2x = -10 Divide both sides by '2' Hence x = -5 .
5x-3 = 11+12x 5x-12x = 11+3 -7x = 14 x = -2
7X = -5X + 24 add 5X to each side 12X = 24 divide both sides by 12 X = 2 check 7(2) =-5(2) + 24 14 = 14
7x = 5+5x 7x-5x = 5 2x = 5 x = 2.5
x=6
7x-5x=8 2x=8 x=4
It is: 12x
7x + 8 = 5x + 327x = 5x + 242x = 24x = 12hope this helps
x=12
5x + 17 = 7x - 123 123 + 17 = 7x - 5x 140 = 2x x = 140 ÷ 2 x = 70
