we can distribute the negative... and distribute the -2 until we find an equation that equals 5-2m

You would open up the brackets for each of the choices. Like your previous problem.

wait a second ... distribute the -2 for
7-2(m+1)

7-2m-2

- oleg3321

yes -2m

- UsukiDoll

now what's 7-2 ?

- anonymous

5

- oleg3321

idk what is it lol 5

- UsukiDoll

yes it is 5.. so we have 5-2m... isn't that the same as the question from earlier?

- oleg3321

@UsukiDoll give me a medal please

- anonymous

Practice makes perfect. Don't forget your variables!

- UsukiDoll

it should be
7-2(m+1) = 5-2m
7-2m-2=5-2m
5-2m=5-2m

- UsukiDoll

no @oleg3321 you gave the wrong answer... the third option is already out thanks to -2 x -2 which is 4

- oleg3321

oh my mad. and ok it ok i messed up a little

- anonymous

sooo its 7 - (2m - 5)

- UsukiDoll

k I'll give a medal anyway since you've admitted to your errors @oleg3321

- oleg3321

thank you i appretiate it

- anonymous

7 - 2 (1 +1)
5 times 2
7

- UsukiDoll

that one shouldn't be there .. and 5 x 2 = 10
here's what I wrote again
7-2(m+1) = 5-2m
7-2m-2=5-2m
5-2m=5-2m

- anonymous

no i got this i get it because 7-2 is 5 then 1+19because of the m and then that makes it 7 -2 ( m + 1)
