what is an example of a pair of equations

x+y=9

2x-y = 3

solve them for me please.

An example of a pair of equations is the following system:

Equation 1: 2x + 3y = 10
Equation 2: x - 2y = 5

To understand how this pair of equations was formed, let's break it down:

Equation 1 states that 2 times the variable x plus 3 times the variable y is equal to 10.

Equation 2 states that the variable x minus 2 times the variable y is equal to 5.

These two equations together form a pair or a system of equations. The goal is to find the values of x and y that satisfy both equations simultaneously. This is known as solving the system of equations.
