Answer:
9 is the answer.
Explanation:
Given:
We can tell that '3x + 6y' is basically '15 x 3' because the whole equation has been multiplied by three. Therefore, 3x + 6y must equal 45.
=> 3x + 6y = 45
But we need to divide 45 by 5 to get the solution because the 3x + 6y has also been divided by 5.
=> 45/5
=> 9
Therefore, 9 is the answer.
