The dependent variable is y
the dependent variable is usually isolated on one side of the equation
-hope that helps
For this case we must solve the following equation:

To solve we follow the steps below:
Subtracting 6 from both sides of the equation:

Equal signs are added and the same sign is placed:

We multiply by -1 on both sides of the equation:

We divide between 4 on both sides of the equation:

Thus, the solution of the equation is 
Answer:

Answer:
2 tee shirts
5 sleeves
Step-by-step explanation:
Let the number of shortsleeves be S and longsleeves L.
Total is 7
That is
L + S = 7
Total money spent is $73, while shorts cost 9 and longs 11
Hence,
9S + 11L = 73
We now have two equations we can solve simultaneously. From the first equation,
L = 7 - S
Putting this in equation 2
9s + 11(7 - S) = 73
9s + 77 - 11S = 73
2S = 4
S = 2
Since s = 2, then L = 5

4000: ??? : ???
Divide 4000 by two, which is 2000.
2+5+8= 15
2000 times 15 = 30,000
So the answer is B) $30,000
