Question

-15.6 = -3.9r
please include an explanation of how you got your answer :) thanks

Answer 1

Here is the equation:

`-15.6 = -3.9r`

Since both decimals are negative, the answer will be positive.

• Negative times Negative = Positive

Divide both sides by -3.9 to leave the variable alone:

`-15.6 / -3.9 = -3.9r / -3.9 \\ 4 = r`

r is equal to 4 → r = 4
