Question

simplify
a = ) A- {2b{3a-(2b-3c)}​

Answer 1

Step-by-step explanation:

We first remove the innermost grouping symbol ( ), then { } and then [ ]

We have,

a–[2b–{3a–(2b−3c)}]

=a–[2b–{3a–2b+3c}]

=a–[2b–3a+2b–3c]

=a–2b+3a–2b+3c

Rearranging and collecting the like terms, we get:

=a–3a–2b–2b+3c

=4a–4b+3c
