Use the elimination method to solve the system of equations . choose the correct ordered pair -3y = x - 5 x + 5y = 7

.

Step-by-step explanation:

We have been given a system of equations. We are asked to solve our given system using elimination method.

First of all, we will gather all terms of both equations on left side as shown below:

Adding equation (1) and (2), we will get:

Now, we will add 2 on both sides of our equation as shown below:

Upon substituting in equation (2), we will get:

Therefore, the solution for our given system of equations would be .
