Respuesta :
2x + y = 3
x = 2y - 1
.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1
x = 2y - 1

As per linear equation, the value of 'x' is 1 and 'y' is 1.
What is a linear equation?
"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation."
Given linear equations are:
2x + y = 3 (1)
x = 2y - 1
⇒ x - 2y = -1 (2)
Now, multiplying equation (1) with 2 and then add with equation (2), we get:
4x + 2y + x - 2y = 6 - 1
⇒ 5x = 5
⇒ x = 1
Therefore, putting the value of 'x' in equation (1), we get:
2 × 1 + y = 3
⇒ y = 3 - 2
⇒ y = 1
