Answer:
g equals 21.
Step-by-step explanation:
3 * (7 + 10) = g + 30
Add 7 and 10 to get 17.
3 * 17 = g + 30
Multiply 3 and 17 to get 51.
51 = g + 30
Swap sides so all variables are on the left side.
g + 30 = 51
Subtract 30 from both sides.
g = 51 - 30
Subtract 30 from 51 to get 21.
g = 21
g equalling 21 is your final answer.
