The answer for 4x + 6y = 8 ,3x - y = - 5 is x=-16/11, y= 7/11.

3x - y = - 5 ,y=3x+5, put in 4x + 6y = 8

4x+6(3x+5)=8.

4x+18x+30=8

22x=-32

x=-32/22=-16/11.

y=3x+5

=3x(-16/11)+5

=-48/11+5

=7/11.

3x - y = - 5 ,y=3x+5, put in 4x + 6y = 8

4x+6(3x+5)=8.

4x+18x+30=8

22x=-32

x=-32/22=-16/11.

y=3x+5

=3x(-16/11)+5

=-48/11+5

=7/11.
