Solve the equation 3x/ 8 - 4x/3 =4

Virty [35]

Answer:

x = -96/23

Step-by-step explanation

$\frac{3x}{8}$ - $\frac{4x}{3}$ = 4

multiply each side of equation by 24 to eliminate denominators

(24) $\frac{3x}{8}$ - $\frac{4x}{3}$ = 4 (24)

3(3x) - 8(4x) = 96

9x - 32x = 96

-23x = 96

x = -96/23
