How could you solve for x in the problem 3x+7=-x-1

lukranit [14]

Hello there!

$3x+7=-x-1\\$

Explanation:

↓↓↓↓↓↓↓↓↓↓↓↓

First you had to subtract by 7 from both sides of the equation.

$3x+7-7=-x-1-7$

Simplify

$3x=-x-8$

Then you add by x from both sides of the equation.

$3x+x=-x-8+x$

Simplify

$4x=-8$

Divide by 4 from both sides of the equation.

$\frac{4x}{4}=\frac{-8}{4}$

Simplify it should be the correct answer.

$x=-2$

Answer⇒⇒⇒x=-2

Hope this helps!
