\[\frac{x}{27}=\frac{-15}{9}\]
1
Move the negative sign to the left.
x27=−159\frac{x}{27}=-\frac{15}{9}

2
Simplify  159\frac{15}{9}  to  53\frac{5}{3}.
x27=−53\frac{x}{27}=-\frac{5}{3}

3
Multiply both sides by 2727.
x=−53×27x=-\frac{5}{3}\times 27

4
Use this rule: ab×c=acb\frac{a}{b} \times c=\frac{ac}{b}.
x=−5×273x=-\frac{5\times 27}{3}

5
Simplify  5×275\times 27  to  135135.
x=−1353x=-\frac{135}{3}

6
Simplify  1353\frac{135}{3}  to  4545.
x=−45x=-45
