Question

3. Subtract 4a - b-C+3 from the sum of 30 - 5b +
3c and 20 + 4b-5c.​

Answer 1

Answer:

47-4a-4c this is the ans

Answer 2

Answer:

(4a-b-c+3) - (30-5b+3c) - (20+4b-5c)

As it is minus then we must change the sign.

so,

4a-b-c+3 -30+5b-3c -20-4b+5c

then arrange

4a -b+5b-4b -c-3c+5c +3-30-20

4a -b+b -c+2c -3-50

(-b and +b will get cancelled as they are the opposite signs)

:- 4a +1c -47 is the answee
