To figure this out, use substitution. Solve for x in the first equation. You shoud end up with . Then plug that into the second equation and after adding like terms get . So y must be zero, since 0+4=4 and 20y+4=4. 20y just takes the place of zero. So y=0. Plug y into the first original equation (4x-5y=2). Get . So 4x=2. Divide both sides by 4 and get x=2/4 which is reduced to 1/2. So y=0 and x=1/2. Wanna check these values? plug them both back into the second original equation. Did you end up with ? See? It works!
