Question

7=8 + r/15 Simplify, with steps pleaseee

Answer 1

Answer:

$7 = 8 + \frac{r}{15} \\ 7 - 8 = \frac{r}{15} \\ - 1 = \frac{r}{15} \\ \therefore \: r = - 15$

Answer 2

Answer:

Step-by-step explanation:

I think you mean solve for r, do you not?

7   =   8 + r/15                          Subtract 8 from both sides

-8     -8

-1   =  r/15                                Multiply both sides by 15

-1 * 15 = 15 * r / 15                   Combine

-15            = r
