Both expressions equal 5 when substituting 2 for x because the expressions are equivalent. Hope this helped :D
First, subtract 2/3 from both sides and you get

Then multiply both sides by 6/5 and you get
We go from 10x+20 = 50 to 10x = 30 after we subtract 20 from both sides. So we use the subtraction property (of equality).
