Question

Expand and simplify 2(3a-6b)-7(2a+3b-5c)

Answer 1

Given:

An algrbraic expression 2(3a - 6b) - 7(2a + 3b - 5c)

To find:

Expand and simplify 2(3a - 6b) - 7(2a + 3b - 5c)

Solution:

From given, we have,

2 (3a - 6b) - 7 (2a + 3b - 5c)

= 2 (3a) - 2 (6b) - 7 (2a) - 7 (3b) + 7 (5c)

= 6a - 12b - 14a - 21b + 35c

= (6 - 14) a - (12 + 21) b + 35c

= -8a - 33b + 35c

Hence the simplification of 2(3a - 6b) - 7(2a + 3b - 5c) is -8a - 33b + 35c
