What does this equal j-9.2=22.5

Answers

the answer is 31.7 because to get j by itself you add 9.2 to 22.5
you have to get j by itself and since the operation being used is subtraction, you have to use the opposite, which is addition. so you add 9.2 to both sides, which gets rid of 9.2 on the variable side and on the the numerical side 22.5+9.2=31.7. i don't really know how explain a simple one step equation 
j-9.2=22.5\nj=31.7
