Answer:
m =
Step-by-step explanation:
m - = 1 -
Multiply through by 6 ( the LCM of 2 and 3 ) to clear the fractions
6m - 3(m - 1) = 6 - 2(m - 2) ← distribute parenthesis on both sides
6m - 3m + 3 = 6 - 2m + 4 , that is
3m + 3 = - 2m + 10 ( add 2m to both sides )
5m + 3 = 10 ( subtract 3 from both sides )
5m = 7 ( divide both sides by 5 )
m =
