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
