Answer: r = 7

Step-by-step explanation:

Subtract 12 from both sides to isolate the r variable. You have -42 = -6r. Divide both sides by -6 to get r by itself and you get r = 7. Verify by substituting 7 as the r value and solving the equation.

Answer:

r=7

Step-by-step explanation:

First subtract 12 from both sides

Now you have -42=-6r

Next divide each side by -6

Now you have 7=r

And that is your answer
