Answer :
The solution is a set of numbers x,y that satisfy both equations.
x+y =3
x = 3 -y
4x - y = -38
4(3 -y) = -38
12 -4y = -38
-4y = -50
y= 12.5
x = 3 -y
x = 3 -12.5
x= -9.5
The x-coordinate is -9.5, y is 12.5
x+y =3
x = 3 -y
4x - y = -38
4(3 -y) = -38
12 -4y = -38
-4y = -50
y= 12.5
x = 3 -y
x = 3 -12.5
x= -9.5
The x-coordinate is -9.5, y is 12.5
