Solving Equations with Grouping Symbols:

3(g-3)=6

Please explain how to do this

Rules:

Combine like terms
Solve by using inverse operations
Answered by Ms. Sue
3(g-3)=6

3g - 9 = 6

3g - 9 + 9 = 6 + 9

3g = 15

g = 15/3

g = 5

What about :
5(2c+7)=80
Answered by Cassie
I don't understand it still
Answered by Ms. Sue
5(2c+7)=80

Parentheses means multiply.

10c + 35 = 80

Get the knowns on one side -- so subtract 35 from each side.

10c + 35 - 35 = 80 - 35

10c = 45

Divide both sides by 10

c = 45/10

c = 4.5

Good morning I am actually trying to help my nephew who lives with me,he has a hard time understanding math and how to solve the equations. Is there anyone who can give me help on solving this & like problems with step by step (written in words explaining exactly how to solve it). 3(c+5)=12. 5(4d+8)=40. -(2k-11)=7. 3/4(4x+8)=-12. 1/3(9c-36)=-9. Any help would be greatly appreciated! Thank you Ann
