    r=8

    Step-by-step explanation:

    To solve for r, we have to get r by itself. We have to preform the opposite of what is being done to the equation.

    r/4-17 = - 15

    First, move all the numbers to the same side. Add 17 to both sides, since it is being subtracted.

    r/4-17+17 = - 15+17

    r/4 = 2

    Now, we have r/4 alone. r is being divided by 4. To undo this, multiply both sides by 4.

    4*r/4=2*4

    r=8
