Step-by-step explanation:
This question can be solved by a system of equations.
Four white chocolate truffles (W) cost the same as three dark chocolate truffles (D).
So

Answer:
One. It is a = 7/3
Step-by-step explanation:
Let's simplify the equation 6a − 3a − 6 = −2 + 3 by combining like terms:
3a - 6 = 1
Adding 6 to both sides, we get:
3a = 7.
Dividing both sides by 3, we get
a = 7/3.
This equation has ONE solution, which is a = 7/3.
