Answer: r=-56

Step-by-step explanation:

multiply 7 on both sides

[tex]\frac{7r}{7}=7\left(-8\right)[/tex]

7*-8=-56

7 and 7 is eliminated

so x=-56

Answer:

r= -56

Step-by-step explanation:

The equation given is:

[tex]\frac{r}{7}= -8[/tex]

We want to solve for r. In order to do this, we must get r by itself.

Currently, r is being divided by 7. We want to perform the inverse, which is multiplication. Therefore, we should multiply both sides of the equation by 7.

[tex]7*\frac{r}{7}= -8 * 7[/tex]

[tex]r=-8*7[/tex]

[tex]r= -56[/tex]

Let's check our solution. Substitute -56 back in for r and solve.

[tex]\frac{r}{7}= -8[/tex]

[tex]\frac{-56}{7}= -8[/tex]

[tex]-8=-8[/tex]

Both sides of the equation are the same, so we know our answer is correct.
