Answer 2

To solve the given system of equations:

Equation 1: x - y = 7 Equation 2: x + y = 1

There are multiple methods to solve this system. Here, I'll demonstrate the elimination method:

Step 1: Add the two equations together to eliminate the variable "y." (x - y) + (x + y) = 7 + 1 2x = 8

Step 2: Solve for "x" by dividing both sides of the equation by 2. 2x/2 = 8/2 x = 4

Step 3: Substitute the value of "x" into either of the original equations to find the value of "y." Let's use Equation 2. 4 + y = 1 y = 1 - 4 y = -3

Therefore, the solution to the system of equations is: x = 4 y = -3
