You have to isolate x so the opposite of addition is subtraction.

x + 2.79 = 9.93

Subtract 2.79 to both sides to cancel it out on the left.

x = 9.93 - 2.79

x = 7.14

Or if you want a simpler way, just subtract 2.79 from 9.93, that's basically the same thing that you will wind up doing later on with the other strategy... The answer is still 7.14
