Question

-3(_x + 4) = 9x – 12 Using the distributive property, what number would go in the blank in order for the given statement to be correct? ​

Answer 1

-3(-3x + 4) = 9x - 12

Explanation:

-3( Ax + 4) = 9x - 12

-3Ax -12 = 9x - 12

Equating coefficients of x terms on both sides :

-3A = 9

A = -3

Therefore, -3(-3x + 4) = 9x - 12
