In what way you want to solve the system?

5x%2B2y=4, small readjustment

use this to substitute: y=1-4x.

5x%2B2%281-4x%29=4
5x%2B2-8x=4
-3x=2
highlight%28x=-2%2F3%29

Use that to evaluate y.
y=1-4%28-2%2F3%29
y=3%2F3%2B8%2F3
highlight%28y=11%2F3%29



Another way:

system%28y=-4x%2B1%2Cy=-5x%2F2%2B2%29
