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

Practice makes perfect. Don't forget your variables!
UsukiDoll
  • UsukiDoll
it should be 7-2(m+1) = 5-2m 7-2m-2=5-2m 5-2m=5-2m
UsukiDoll
  • UsukiDoll
no @oleg3321 you gave the wrong answer... the third option is already out thanks to -2 x -2 which is 4
oleg3321
  • oleg3321
oh my mad. and ok it ok i messed up a little
anonymous
  • anonymous
sooo its 7 - (2m - 5)
UsukiDoll

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