Solve for x: one over four (4x + 15) = 24 How do you figure out the answer to this question?

And 81/4=20 1/4!  And 20.25!

So, I believe we have  ...   (1/4)(4x + 15) = 24      muliply both sides by 4

4x + 15 = 96      subtract 15 from both sides

4x = 81              diivide both sides by 4

x = 81 / 4
