Answer
In order to solve a system of three linear equations, we first isolate one of the variables. After solving for this variable, we use its value to solve for the other variables. (Note, the numbers to the left of the work are the equation numbers, where the top equation in the system is equation one while the bottom equation in the system, as listed in the textbook, is equation three.)
