Question

Solve for x and y: 10x=5y+5 y=2x-1

Answer 1

So there are infinite solutions along the line y = 2x-1

Explanation:

10x=5y+5

y=2x-1

Substitute y into the first equation

10x = 5(2x-1) +5

10x = 10x-5+5

10x = 10x

This is always true

So there are infinite solutions along the line y = 2x-1
