Question

Solve for the unknown variable. 144=-12(x+5)

Answer 1

Explanation:

114=-12(x+5)

Use the Distributive Property of Multiplication (distribute the -12 to the x and 5).

144=-12x-60

Add 60 to both sides of the equal sign to get -12x by itself.

144+60=-12x-60+60

204=-12x

Divide both sides of the equal sign to isolate the variable.

204/-12=-12x/-12

-17=x (<<<Answer)

Answer 2

Answer: x=-17

Explanation:

We first distribute the -12 across to the (x+5)

144=-12(x+5)

144=-12x-60

Then, we add 60 to both sides.

204 = -12x

Lastly, we divide the equation by -12.

204/-12 = -12x/-12

-17 = x
