man owns cows and chickens that total 30

when the son couned them his answer was 74 legs how many chicken did the farmer own

x=cows y=chickens

x+y=30

4x+2y =74

please finish for me

Solve one equation for one variable. Take the first one, it's easier. Solve for x. You'll get x = 30 - y. Plug this new value in for x in the second equation: 4(30-y) + 2y = 74. Now, solve for y. You should be able to plug in a solution for y into the first equation to get an answer for x.
