Answer 2

To solve this system of equations:

1. 2x - y = 117
2. x - y = 26

You can use the method of substitution or elimination. I'll show you the elimination method:

First, subtract equation (2) from equation (1) to eliminate the variable "y":

(2x - y) - (x - y) = 117 - 26

Simplify:

x = 91

Now that you have found the value of x, you can substitute it back into either equation (1) or equation (2) to find the value of y. We'll use equation (2) for this:

x - y = 26

91 - y = 26

Now, solve for y:

y = 91 - 26 y = 65

So, the solution to the system of equations is:

x = 91 y = 65
