how ton solve the system for x and y as an ordered pair

y=5x+8

y=3x+6

y=5x+8 multiply by 3

y=3x+6 multiply by 5

3y=15x+24 equation i

5y=15x+30 equation ii

subtract the two equations i.e equation i from equation ii to get

2y=6

therefore

y=3

to get x substitute y in eqn i

3=5x+8

5x=-8+3

5x=-5

x=-1
