Answer:

If I'm correct, you're looking for X?

X--8

Explanation:

Let's solve your equation step-by-step.

−13+16=−3(x+7)

Step 1: Simplify both sides of the equation.

−13+16=−3(x+7)

−13+16=(−3)(x)+(−3)(7)(Distribute)

−13+16=−3x+−21

(−13+16)=−3x−21(Combine Like Terms)

3=−3x−21

3=−3x−21

Step 2: Flip the equation.

−3x−21=3

Step 3: Add 21 to both sides.

−3x−21+21=3+21

−3x=24

Step 4: Divide both sides by -3.

−3x

−3

=

24

−3

x=−8
