## anonymous one year ago Explain how opposites are applied when solving one-step equations. How do you know what to use to solve a one-step equation? Be specific and complete.

HI!!

2. anonymous

hello

3. misty1212

what the monkey is a "one step" equation?

4. misty1212

does that mean you can get the answer in "one step"?

5. anonymous

when you only have to do one step to solve it i think

6. anonymous

yeah

7. misty1212

lol some math teacher must have coined that phrase

8. anonymous

I think I know the answer just want to make sure with someone

9. misty1212

ok so it is something like $x+5=9$i guess you are supposed to the the "opposite" of $$5$$ is $$-5$$ so we can solve via $x+5-5=9-5\\ x=4$

10. anonymous

yes spot on

11. misty1212

or if you have $x-4=7$ then the "opposite" of $$-4$$ is $$4$$ so $x-4+4=7+4\\ x=11$

12. anonymous

yeah

13. misty1212

wonder if they taught them this is math education school it is certainly not math that is for sure

14. anonymous

it is

15. misty1212

maybe include $2x=10$ the "opposite" of multiplying by 2 is dividing by 2, so $2x=10\\ \frac{2x}{2}=\frac{10}{2}\\ x=5$

16. anonymous

okay thank you :)
