Using the substitution method to solve the linear system the value of x and y is 1 and 2 respectively.
<h3>What is the linear system?</h3>
It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width.
Given
The equations are shown below.
y = 5 - 3x .....1
5x - 4y = -3 .....2
Substitute equation 1 in equation 2. Then

Then substitute the value of x in equation 1.

Thus, the value of x and y is 1 and 2 respectively.

Answer:
The measure of angle x is 122.5 degrees.
The measure of angle y is 57.5 degrees
Step-by-step explanation:
180=y+x
y=x-65
180= (x-65)+x
180=2x-65
245=2x
x=122.5
y=122.5-65= 57.5
