2. 4 77/100
3. 10.7
4. 6 57/100
Option B is your answer.
3/5x - 5 + 5/5x - 4 = - 1
8/5x - 9 = - 1
8/5x = - 1+ 9
8/5x = 8
Multiply both sides by 5/8 (the reciprocal of the coefficient) to isolate variable X.
(5/8)(8/5x) = 8(5/8)
x = 40/8
x = 5
4u3 - 7u + 9. Sorry if I'm wrong, hope this helped! ヾ(〃^∇^)ノ
