Question

Simplify:

2a − 3b − [3a − 2b − {a − c − (a − 2b)}]

Sum

Solution

2a − 3b − [3a − 2b − {a − c − (a − 2b)}]
We will first remove the innermost grouping symbol ( ), followed by { } and then [ ].

∴ 2a − 3b − [3a − 2b − {a − c − (a − 2b)}]
= 2a − 3b − [3a − 2b − {a − c − a + 2b}]
= 2a − 3b − [3a − 2b − {− c + 2b}]
= 2a − 3b − [3a − 2b + c − 2b]
= 2a − 3b − [3a − 4b + c ]
= 2a − 3b − 3a + 4b − c
= − a + b − c
