Answer:
??
Step-by-step explanation:
4x+6y=8
3x+y=9
y = 9 - 3x
4x + 6(9-3x) = 8
4x + 54 - 18x = 8
14x = 46
x = 23/7
y = 9 - 3(23/7)
y = 9 - 69/7
y = - 6/7
The second option is the correct answer

The expression given to us is:

Herein, we can simplify it by opening up the bracket and multiplying each term inside the bracket by the term which is outside the bracket.
Thus, we get:


Rearranging the above expression in descending order of power we get:

From the given options we can see this is the second option. Hence the second option is the correct answer.
