For this case we propose a system of equations:
x: Let the variable representing the quantity of Granny Smith apples
y: Let the variable representing the number of Gala apples
According to the statement we have:

From the first equation we have to:

replacing in the second equation:

So, Carl bought 7 Gala apples
On the other hand:

So, Carl bought 12 Granny Smith apples
Answer:
Carl bought 7 Gala apples and 12 Granny Smith apples
Solve (2x - 1)(3x^2 - 9x - 4)
=
Answer:
<h2>

</h2>
Step-by-step explanation:
32base x means 
Similarly, 32base x+51base y equals to 
and 23base x +42 base y means 
As per the given condition, 
Putting,
in
, we get
