Answer:

$x=\frac{10}{3}$

Step-by-step explanation:

$3x-3(4+x)=\frac{3}{4}(3x+2)-1$

Solve the parenthesis ↑

$3x-12+3x=\frac{9}{4}x+\frac{6}{4}-1$

Multiply everything by 4 to get rid of the denominators.

$\frac{12x}{4}-\frac{48}{4}+\frac{12x}{4}=\frac{9}{4}x+\frac{6}{4}-\frac{4}{4}$

Rid the denominators.

$12x-48+12x=9x+6-4$

Solve.

$12x+12x-9x=6-4+48$

$15x=50$

$x=\frac{50}{15}$

Simplify.

$x=\frac{10}{3}$
