7 x 4 = 28
28 - 14 = 14
Therefore 5x = 14
14/5 = 2.8
Therefore x = 2.8

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 + 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
