Question 76951
3(x+4)

This implies that the equation is equal to 0.

Using the distributive property, you would multiply each term inside the parentheses by whatever is outside of the parentheses.

3(x+4)  comes out to be:
3x+12=0

Subtract 12 from both sides to get:  

3x= -12

divide both sides by 3 to get:

x = -4
