Solving Equations with Grouping Symbols:
3(g3)=6
Please explain how to do this
Rules:
Use Distributive Property
Combine like terms
Solve by using inverse operations

3(g3)=6
3g  9 = 6
3g  9 + 9 = 6 + 9
3g = 15
g = 15/3
g = 5

What about :
5(2c+7)=80

Math  Cassie, Wednesday, January 18, 2012 at 5:52pm
I don't understand it still

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

Math/solving twostep equatios(distributive properties)  ann, Friday, September 25, 2015 at 5:20am
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. (2k11)=7. 3/4(4x+8)=12. 1/3(9c36)=9. Any help would be greatly appreciated! Thank you Ann
