Solve this system by substitution: 2x3y=12
x4y=6
Slve this system by elimination: 8x+5y=22
6x+ 2y=13

In the second equation,
x=4y+6 Put that in the first equation for x, and solve for y.
In the second system, multipy the first equation by 2, and the second by 5
16x+10y=24
30x+10y=44
Now subtract one equation from the other. 
Solve this system using substitution. Write your answer as an ordered pair. x = 3 3x – 4y = 37
