Thus you have
Since the right side of each of the equations is equal to the same thing, y, they must be equal. Thus
Solve this equation for x. I want to show you another way to solve this problem. You start with
Since the left side of the first equation is equal to 2 and the left side of the second equation is equal to 5, if you add the two left sides you must get 2 + 5 = 7. Thus
Simplifying this equation gives
Solve for x. I hope this helps,
