My daughter has an assignment in math that includes this equation:
I've tried to help her with a scale. We've figured that you subtract 5 from each equation so its not -6b = -15. Is this correct and can you help us figure out the next step? Her name is Shelley and she is in 8th grade (independent study program).
Add 10 to both sides to get
Now add 6b to both sides and the equation becomes
Notice that both 15 and 6 are divisible by 3 so divide both sides by 3 and you have
Finally divide both sides by 2 to get
For this last step it may help to think of something familiar. If two b's cost $5 then one b costs $2.50
