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
