Answer: -10

Step-by-step explanation:

Again Let the unknown  number be variable = X

The statement stated thus,

4( x + 7 )  = -12

Open the bracket by multiplying by 4 and solve for x

 4x + 28  = -12

         4x  = -12 -28

         4x = -40

Now divide by the coefficient of x which is 4 to get the variable x

           x = -10

Therefore, the value of the number is -10
