x=-42/5

Explanation:

On the right hand side, start by distributing the 2 throughout the expression (9x+10). So 2times9=18 and 2times10=20, giving:

13x-22=18x+20

Next, add 22 to both sides of the equation.

13x=18x+42

Next, subtract 18x from both sides.

-5x=42

Finally, divide both sides by -5

x=-42/5
