1) 9g+7h=9g-7h+g
Combined Like Terms: 9g+7h=10g-7h
Subtract 7 from both sides: -7h -7h
9g=10g-14h
Subtract 10 from both sides: -10g -10g
-g=-14h
Divide -1 from both sides: -g/-1=-14h/-1
Answer: g=14h
2) y=x-21y
Add 21 to both sides: +21y +21y
22y=x
Divide 22 from both sides: 22y/22=x/22
Answer: y=x/22

1. First: combine "like" terms on the right side >
9g + 7h = 9g - 7h+ g
9g + 7h = 10g - 7h
Sec: solve for "g" and keep it on one side (left) > subtract 10g from both sides >
9g + 7h -10g = 10g -10g - 7h
- g + 7h = -7h
Third: subtract 7h from both sides > the negative can't be negative so, change all of the signs >
- g + 7h -7h = -7h - 7h
- g = -14h
g = 14h
2. follow the same format to solve for "y"

9g+7h=9G-7h+g
9g+7h=10g-7h
14h=g
y= x-21y its already solved for y if it's y=
-x=-22y
x/22=y

1)9g+7h=9g-7h+g
Combine like terms:

Add 7h from both sides:
9g+14h=10g
Subtract 9g from both sides:
g=14h
2)y=x-21y
Add 21y from both sides:
22y=x
Divide 22 from both sides:
y=x/22
