oppression $\frac{3x-4}{4} = \frac{x}{3} +2$
$12* \frac{3x-4}{4} =12* \frac{x}{3} +12*2$
$3(3x-4)=4x+24$
$9x-12=4x+24$
$9x-4x=24+12$
$5x=36$
$x=7,2$

vasilsenkin $\frac{3}{4}x - 1= \frac{1}{3}x + 2 \\ 
 \frac{3}{4}x- \frac{1}{3}x=2+1 \\ 
 \frac{9}{12}x- \frac{4}{12}x=3 \\ 
 \frac{5}{12}x=3 \\ 
x=3: \frac{5}{12} \\ 
x=3* \frac{12}{5} \\ 
x= \frac{36}{5} =7 \frac{1}{5}$
