Answer 1

Answer:

the answer is B

$3( \frac{7}{5} x + 4) - 2( \frac{ 3}{2} - \frac{5}{4} x)$

$(3 \times \frac{7}{5} x) + (3 \times 4) - 2( \frac{3}{2} - \frac{5}{4} x)$

$\frac{21}{5} x + 12 - 2( \frac{3}{2} - \frac{5}{4} x)$

$\frac{21}{5} x + 12 + ( - 2 \times \frac{3}{2} ) + ( - 2 \times ( - \frac{5}{4} x))$

$\frac{21}{5} x + 12 - 3 + \frac{5}{2} x$

$\frac{21}{5}x + \frac{5}{2} x + 12 - 3$

$\frac{67}{10}x - 9$
