The method of solving this equation looks fine to me and the answer is correct since 3 + x/2=10 is x/2=10-3 and so x/2 =7 and so x = 14 as shown and checking, then subsituting 14 for x then x/2=7 = 10-3 so therefore it is fine the way it is.

| (0.2) ÷ 8.9 | x 100

= 2.2

So, the percent error is 2.2%
