I thought maybe to subtract 22 from 7. But that doesn't seem very...well right...

Because you are subtracting 7 from x, You actually want to add it on both sides of the equation.

think of the equation like a balance... you want to get that " - 7" off the right side, but to keep it balance, you have to add seven to both sides... on the right, -7 + 7 = 0, leaving x. On the left, -22+7 = -15

Don't make that see-saw fall left or right, keep it balanced by doing the same thing to both sides... :) (silly example, but it can keep your mind focused)

add 7 to the -22 to get -15 and the answer is x= -15
