Answer:
A.) x = 25
Step-by-step explanation:
Start off with the original problem
x - 7 = 18
1.) The question is looking for what x is equal to, so you need to get x on one side of the equal sign by itself. To do this, do the opposite of what is stopping it from being by itself. In this case, it's a -7. Make sure to do it on both sides of the equation to keep it balanced.
x -7 +7 = 18 +7
(the -7 and +7 cancel each other out)
x = 25
