## Elementary Algebra

$-1$
The problem must be worked in the order of PEMDAS (parentheses (or fraction bars), exponents, multiplication, division, addition, and subtraction). $\frac{5(-9) - 6(-7)}{3}$ can be divided into $\frac{5(-9)}{3}$$-$$\frac{6(-7)}{3}$ Doing multiplication and division, the fractions can be evaluated to: $-15$ $-$ $(-14)$ $-15 + (14) =-1$
