Answer:

#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#
