TO DETERMINE

To subtract a - 2b - 3c from 3a - 7b + 4c

EVALUATION

Here we have to subtract a - 2b - 3c from 3a - 7b + 4c

So the given expressions are

a - 2b - 3c from 3a - 7b + 4c

Subtrahend = a - 2b - 3c

Minuend = 3a - 7b + 4c

Subtracting we get -

The required result

= ( 3a - 7b + 4c ) - ( a - 2b - 3c )

= 3a - 7b + 4c - a + 2b + 3c

= 3a - a - 7b + 2b + 4c + 3c

= 2a - 5b + 7c
