hello

misty1212 · Answer

what the monkey is a "one step" equation?

misty1212 · Answer

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

anonymous · Answer

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

anonymous · Answer

yeah

misty1212 · Answer

lol some math teacher must have coined that phrase

anonymous · Answer

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

misty1212 · Answer

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 
$$x+5-5=9-5\
x=4$$

anonymous · Answer

yes spot on

misty1212 · Answer

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

anonymous · Answer

yeah

misty1212 · Answer

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

anonymous · Answer

it is

misty1212 · Answer

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