Take away 31 from 31 & you get 0, then 150-31=119. 119 divided by 14 =8.5 so x=8.5

150 = 14x + 31
-31 - 31
------------------
119 = 14x
÷14 ÷14
------------------
8.5 = x

X = 8.5

Don't get stumped

8.5. If you subtract 31 from 31, it equals 0 and 150-31=119. 119 divided by 14 equals 8.5.😁

The answer is 8.5 because you first have to do 31-31 which cancels out. Then do 150-31 which is 119. Then you have to divide by 14 which would make x=8.5

The answer is 8.5
Subtract 31 from 150. You get 119. Divde 119 and 14. You get zero and 8.5.
