Question

Subtract (13x + 12y − 5) from (27x + 5y − 43)

Answer 1

• Here, we need to subtract 13x + 12y − 5 from (27x + 5y − 43)

• Required expression:

(27x + 5y − 43) – ( 13x + 12y − 5)

• First, we expand the brackets and change signs of the second expression:

= 27x + 5y − 43 – 13x – 12y + 5

• Next, we group up like terms together and simplify:

= (27x – 13x) + ( 5y – 12y) –43 + 5

= 14x + ( –7y) –38

= 14x – 7y –38, which is the required answer.
