Solve this system by substitution: 2x-3y=12
x-4y=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.
