Answer (3)

4x-16=12 would be the equation. To solve: Add 16 to both sides. 4x=28 Divide by 4. x=7

Say it out loud and you should get your answer like that.
12 = 16 - 4x
Well, 16 - 4 already equals 12, so the x shouldn't have a value over 2.
The x must be a 1.
The equation would be 12 = 16 - 4 x 1.
Hope this helped.

The number is 7, which was found by setting up the equation 12 = 4 x − 16 and solving for x .
