    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.

    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

    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)
