How do you solve these two equations for x? 1.) 60  2x = 70 – 4x 2) 20  8x = 30  16x 1.) 60  2x = 70  4x
60 + 2x = 70 {added 4x to both sides} 2x = 10 {subtracted 60 from both sides} x = 5 {divided both sides by 2} 2.) 20  8x = 30  16x 20 + 8x = 30 {added 16x to both sides} 8x = 10 {subtracted 20 from both sides} x = 10/8 {divided both sides by 8} x = 5/4 {reduced}  Algebra House
