Four times the sum of a number and seven is twenty three.

Step-by-step explanation:

You're going to want to set up an algebraic equation to solve this. It would look like this: 4(x+7)=23. Using distributive property, you'd get 4x+28=23. Subtract 28 from both sides to isolate 4x, and you'd get 4x=-5. Divide by 4 on both sides to isolate x and you'd get x=.

CHECK:

To check, plug in x.

4(+7)=23.

Use distributive property and get +28=23. This simplifies to -5+28=23, which is correct.
