# What is the solution to the system of linear equations?

# 3x - y = 23, 4x + 3y = 48

A system of linear equations is a set of equations that are satisfied by the same set of variables.

## Answer:x = 9,y = 4

We will use the substitution method to solve the system of equations.

**Explanation:**

We have equations, 3x - y = 23 ....(1) and 4x + 3y = 48 ....(2)

From Equation (1), y = 3x - 23 ....(3)

Substitute 3x - 23 for y in Equation (2).

4x + 3(3x - 23) = 48

13x - 69 = 48

13x = 117

x = 9

Now, substitute 9 for x in Equation (3)

y = 3 (9) - 23 = 4
