Answer 2

Hi,

Expression 1 = $9b - 10a + 15$

Expression 2 =$3a + b + 2$

Resultant expression after adding both expression 1 and 2:
Before solving,Always remember like term adds with like term and the same rule is applicable for subtraction.
So,
Addition of both=
$9b - 10a + 15 + 3a + b + 2 \\ = -10a + 3a +9b + b + 15 + 2 \\ = a(-10 + 3) + b(9+ 1) + 17 \\ = -7a +10b + 17 or = 10b-7a+17$
Hope this helps you.
