The solution  to the system of equations is (x, y) = (2, -1).

<h3>What is a system of equations?</h3>

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

WE are given the  system of equations

2x−y=5

y = 2x - 5

y=3x−7

Adding the two equations Then divide by 2

Subtracting the second equation from the first gives;

0 = x -2

x = 2

y = -1

therefore, The solution is (x, y) = (2, -1).

The solution  to the system of equations is (x, y) = (2, -1).
