The sum of three fourths of a number and 1 is 5

Do you need to solve for "a number"?

Let's call it x. So (3/4) x + 1 = 5.

Subtract 1 from both sides because we want to separate that x from everything else.

(3/4) x = 4.

Multiply both sides by 4.

3x = 16.

Divide both sides by 3. x = 16/3.

To test it, (16/3) (3/4) + 1

(48/12) + 1

4 + 1

5
