Question

Solve this equation for r.
4r - 7 = 28

Answer 1

@wishingdust : Well, we need to get the variable by itself. So, you need to take each number from the side of the equation with r and bring it to the other side.

First, we need to remove the -7. So, add 7 to the other side.
Next, divide 4 from the other side.
Once you are done with those steps, you should find your equation to be r = some number.

That should give you your answer.
