- 4 ( t + 7 ) - ( t + 6 ) = 10
- 4 * t - 4 * 7 - t -+ 6 = 10
- 4 t - 28 - t - 6 = 10
- 5 t - 34 = 10 Add 34 to both sides
- 5 t - 34 + 34 = 10 + 34
- 5 t = 44 divide both sides by - 5
t = - 44 / 5 = - 8.8
- 4 ( t + 7 ) - ( t + 6 ) = 10
- 4 ( - 8.8 + 7 ) - ( - 8.8 + 6 ) = 10
- 4 * ( - 1.8 ) - ( - 2.8 ) = 10
7.2 + 2.8 = 10
10 = 10
