Question

Solving a system of linear equations algebraically:

Answer 1

x = 1

Step-by-step explanation (work shown in attached pictures):

1) You can find x by using the elimination method. First, multiply the second equation by -1 in order to make the coefficient of the y-term -1. This makes it so that when we add the two equations, the y-terms will cancel out, leaving the x-terms for us to solve.

2) Now, add the two equations together and cancel the two y-terms out. With the resulting equation, isolate x to find its values. So, the resulting answer is x = 1.
