Answer:

x = 8

Explanation:


(x + 6)/(4) + (x - 3)/(5) = (5x - 4)/(8) \\ \\ (5(x + 6) + 4(x - 3))/(4 * 5) = (5x - 4)/(8) \\ \\ (5x + 30 + 4x - 12)/(20) = (5x - 4)/(8) \\ \\ (9x + 18)/(20) = (5x - 4)/(8) \\ \\ 8(9x + 18) = 20(5x - 4) \\ 72x + 144 = 100x - 80 \\ 144 + 80 = 100x - 72x \\ 224 = 28x \\ \\ x = (224)/(28) \\ \\ \huge \red{ \boxed{x = 8}}

Answer:

x = 8

Explanation:

Simplify both sides:

9/20x + 9/10 = 5/8x + -1/2

Subtract 5/8x from both sides

-7/40x + 9/10 = -1/2

Subtract 9/10 from both sides

-7/40x = -7/5

Multiply both sides by 40/-7

x=8
