Question

Evaluate and simplify if possible:

Answer 1

$\frac{2x(3y - 4z)}{3(5x + 4z)}$   Plug in the given values
$\frac{2(4)(3(-1) - 4(-3)}{3(5(4) + 4(-3)}$   Multiply where needed
$\frac{8(-3 + 12}{3(20 - 12)}$   Add and subtract inside the parentheses
$\frac{8(9)}{3(8)}$   Multiply
$\frac{72}{24}$
