Question

Solve for r 5(r - 10 ) = -51

Answer 1

We need to solve the expression below for "r":

`5\cdot(r-10)=-51`

We need to isolate the "r" variable on the left side to determine its value. To do that we will need to apply the distributive property for the product betwwen 5 and (r-10). We have:

`\begin{gathered} 5r-50=-51 \\ 5r=-51+50 \\ 5r=-1 \\ r=-(1)/(5) \end{gathered}`
