Answer 1

$5x+2y=4\ \ \ \Rightarrow\ \ \ 5x=-2y+4\ \ \ \Rightarrow\ \ \ x=- \frac{2}{5} x+ \frac{4}{5} \\\\5x+2y=4\ \ \ \Rightarrow\ \ \ 2y=-5x+4\ \ \ \Rightarrow\ \ \ y=- \frac{5}{2} x+2$

Answer 2

So 5x+2y=4
if we had more details we could solve this but if you maniplulat the equation you can get
x=(4-2y)/5
and
y=(4-5x)/2
