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
