Write the word sentence as an equation. Then solve.
leonid [27]

Answer:

As an equation: 15 × x = -75

Solved: x = -5

Step-by-step explanation:

15*x = -75

\frac{15*x}{15} = -\frac{75}{15}, Divide by 15 on both sides to solve for x

x=-\frac{75}{15}, The 15 in the numerator cancels out with the denominator

x= -5, because 75/15=5
