Question

SUBTRACT
$3x + 4y - 8x + 8y$
FROM
$2x - 3y + 5x - 7y$
​

Answer 1

Let us first solve the first expression:-

3x + 4y - 8x + 8y

= -5x + 12y

Now,let us solve the second expression:-

2x - 3y + 5x - 7y

= 7x - 10y

Now, THE ANSWER:

7x - 10y -(-5x + 12y)

= 7x - 10y + 5x - 12y

= 12x - 22y

Hence, this is the required answer.
