2x - y = 5
-x + 3y = 5
...
Choose one equation to solve for x or y
...
-x + 3y = 5
Add x to both sides
3y = 5 + x
Subtract 5 from both sides
3y - 5 = x
...
Substitute into the first equation
2(3y-5) - y = 5
Distribute the 2
6y - 10 - y = 5
Combine like terms
5y = 5 + 10
5y = 15
Divide both sides by 5
highlight_green%28y+=+3%29
...
Substitute this value into the x equation
3(3) - 5 = 9 - 5 = highlight_green%28x=4%29
