Answer:
Step-by-step explanation:
A - 15 = 22.......we have to get " A " by itself....so we got to move the -15 to the other side. When u move a number from one side of the equal sign to the other side, u have to change the sign
A = 22 + 15
A = 37 <==
u can also check ur work by subbing in ur answer back into the original equation to see if it is true..
A - 15 = 22......A = 37
37 - 15 = 22
22 = 22 (correct)...so it checks out
