Hello! So...

We are given the following:

Solve for x.

$3x+23+x=7$

====================

1. Group the like terms.

• $3x+x+23=7$

====================

2. Add similar elements ($3x+x=4x$).

• $4x+23=7$

====================

3. Subtract 23 from both sides.

• $4x + 23 - 23 = 7 - 23$

====================

4. Simplify.

• $4x=-16$

====================

5. Divide both sides by 4.

• $\frac{4x}{4} =\frac{-16}{4}$

====================

6. Simplify.

• $x=-4$ (aka. Option A)

====================

Hope this helps!
