Question

6-129. Nick represented the equation 3(2x+4)=-6 on the Equation Mat below. Choose a strategy to solve for x. You may continue to use algebra tiles, or you may use symbols on paper.

Answer 1

Answer:

x = -3

Step-by-step explanation:

You have the following equation:

$3(2x+4)=-6$

you first you distribution property in order to eliminate the parenthesis:

$3*2x+3*4=-6\\\\6x+12=-6$

next, you subtract 12 in both sides of the equation:

$6x+12-12=-6-12\\\\6x=-18$

Finally, you divide the equation by 6 and simplify:

$\frac{6x}{6}=-\frac{18}{6}\\\\x=-3$

hence, the solution to the equation is x = -3
