Answer:
The solution to the system of equations is:
Step-by-step explanation:
Given the system of equations
2x+y=3
x = 2y - 1
solving the system of equations using the elimination method

Arrange equation variables for elimination

Multiply x-2y=-1 by2: 2x-4y=-2

subtracting the equations




now solve -5y = -5 for y

Divide both sides by -5

Simplify

For 2x+y=3 plug in y=1

subtract 1 from both sides

Simplify

Divide both sides by 2

Simplify

Therefore, the solution to the system of equations is:
