Question

How many solutions does 3(x-2)=22-x have

Answer 1

x=7

Explanation:

Start by distributing the 3:

(3)(x)+(3)(−2)=22-x

Now we have:

3x−6=−x+22

Add x to both sides:

3x−6+x=−x+22+x

Now we have:4x−6=22

Add 6 to both sides:

Add x to both sides.

3x−6+x=−x+22+x

4x−6+6=22+6

Now we have

4x=28

Divide both sides by 4

x=7
