y + g = 12 ,2y + 3g = 16
y =12-g
Substitute y =12-g in the equation 2y + 3g = 16.
2(12-g)+ 3g = 16
24-2g+3g=16
24+g=16
g=16-24
g= -8
Substitute g= -8 in the equation y =12-g.
y =12-(-8)
=12+8
y =20

Answer:

y + g = 12 ,2y + 3g = 16

y =12-g

Substitute y =12-g in the equation 2y + 3g = 16.

2(12-g)+ 3g = 16

24-2g+3g=16

24+g=16

g=16-24

g= -8

Substitute g= -8 in the equation y =12-g.

y =12-(-8)

=12+8

y =20
