Answer :
You have to get y by itself and to do that you need to do the opposite of order of operations.
So the opposite of subtraction is addition so you would add 37 to both sides.
It would cancel out itself then leave y by itself while the other side of the equation is 55
Answer: y = 55
Step-by-step explanation: You want to get the variable or y by itself, so you cancel out what number is next to it which is 37, so you add -37 + 37 and that cancels it out.The reason you add them together is because of opposite operations since it was minus you want to add, and what ever you do to one side you have to do to the other, so 18 + 37 is 55 so y is 55
