Answer 1

Solution to the System of Equations

The given system of equations is:

A: x - y = 4 B: 2x - y = 0 C: x - y = 3 D: 3x - y = 2 E: 2x + y = 2 3/4 F: 3x - y = 1 1/4

To find the solution to the system of equations, we can solve it using various methods such as substitution, elimination, or matrix methods. Let's solve it using the elimination method:

First, let's eliminate the variable 'y' from equations A and B. By subtracting equation A from equation B, we get:

(B - A): (2x - y) - (x - y) = 0 - 4 Simplifying, we have: x = -4

Next, let's substitute the value of 'x' into equation A to find the value of 'y':

A: (-4) - y = 4 Simplifying, we have: y = -8

Therefore, the solution to the system of equations is x = -4 and y = -8.
