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
Answer:
subtract 3m from both sides
Step-by-step explanation:
In this question you need to isolate j. First you multiply 11 on both sides to make 3 + j not a fraction anymore.
3 + j = 22.
Then you isolate j by subtracting 3 on both sides since you must cancel the 3's out to isolate j. Then you get an answer of j = 19

Answer:
x = 2
y = 9
Step-by-step explanation:
Opposite sides of a parallelogram are the same length. This relation is used to make equations with the given side lengths.
<u>Top and Bottom</u>
4x +20 = x +26
3x = 6 . . . . . . . . . . . subtract x+20 from both sides
x = 2 . . . . . . . . . divide by 3
<u>Left and Right</u>
7y = 6y + 9
y = 9 . . . . . . . . . subtract 6y from both sides
