Answer:
g = -0.8571428571
Step-by-step explanation:
3g + -9 + 11g + 21 = 0
Reorder the terms:
-9 + 21 + 3g + 11g = 0
Combine like terms: -9 + 21 = 12
12 + 3g + 11g = 0
Combine like terms: 3g + 11g = 14g
12 + 14g = 0
Solving
12 + 14g = 0
Solving for variable 'g'.
Move all terms containing g to the left, all other terms to the right.
Add '-12' to each side of the equation.
12 + -12 + 14g = 0 + -12
Combine like terms: 12 + -12 = 0
0 + 14g = 0 + -12
14g = 0 + -12
Combine like terms: 0 + -12 = -12
14g = -12
Divide each side by '14'.
g = -0.8571428571
Simplifying
g = -0.8571428571
