jackellyn · Answer

Solve for y
3x+y =16
y=16 -3x

Substitute y into second equation
x +4(16-3x)=20
x +64 -3x =20
-2x +64 =20
-2x = -44
x = 22

Substitute x into first equation
3(22) + y =16
66 +y =16
y = -50

your an angel thank you 
ill need to walk threw the ceck ste with ou however ill have to do t when i get back from my appoinment.

jackellyn · Answer

missed a part, this is right. 

x +4(16 -3x) =20
x + 64 -12x =20
-11x +64 =20
-11x = -44
x = 4

3(4) +y =16
12 + y =16
y = 4
