Solve the equation 2(x-4)=-22
Tcecarenko [31]

Hello Lexi!

<u><em>Answer:  ⇒⇒⇒⇒⇒⇒ x=-7</em></u>

__________________________________________________________

Step-by-step explanation:

First you had to divide by 2 from both sides of equation.

\frac{2(x-4)}{2}=\frac{-22}{2}

Simplify.

\frac{2(x-4)}{2}=x-4

\frac{2(x-4)}{2}

Divide by the numbers.

\frac{2}{2}=1

=x-4

\frac{-22}{2}=-11

Apply the fraction rule.

\frac{-22}{2}

=-\frac{22}{2}

Then you divide by the number.

\frac{22}{2}=11

=-11

x-4=-11

Add by 4 from both sides of equation.

x-4+4=-11+4

Simplify it should be the correct answer.

x=-7
