We have to simplify : 3a - [(4 - 3a)/5] - [(a -
4)/6]
3a - [(4 - 3a)/5] - [(a -
4)/6]
Open the
brackets
=> 3a - [4 /5 - 3a/5] - [a/6 -
4/6]
=> 3a - 4/5 + 3a/5 - a/6 +
4/6
add terms with a and the numeric
terms
=> 3a + 3a/5 - a/6 - 4/5 +
4/6
=> 103a/30 -
2/15
Therefore 3a - [(4 - 3a)/5] - [(a -
4)/6] = 103*a/30 - 2/15
