Answer 2

m-2(3-m) 3

-------------- =--------

4(1-m)-5 7

3m-m2-6+2m 3

------------------------=-------

4-4m-5 7

-m2+5m-6 3

---------------------=--------

-4m-1 7

(-m2+5m-6)7=3(-4m-1)

-7m2+35m-42=-12m-3

-7m2+35m+12m-42+3=0

-7m2+47m-39

m=-b+-root b2-4ac

------------------------

2a

=-47+-root (47)2-4(-7)(39)

---------------------------------------

2(-7)

=-47+-root 2209+1092

---------------------------------

-14

=-47+-root 3301

-------------------------

-14

therefore m= -47+root 3301

-----------------------

-14

or

-47- root 3301

-------------------------

-14
