Answer 2

You have to simplify and get each term separately, for you question :
you have to get a's in one term , ax's in one term and finally the x's in separate term .

Simply do this,
( ) a + ( ) ax + ( ) x
Now fill these brackets with coeff.s you've given ..
( -2 ) a + ( 10 - 2 ) ax + ( 12 - 2 ) x = -2 a + 8 ax + 10 x , which is "a"

Let me know if you got it :)
