If there are 26 bags EACH costing $9 then you would use equation A.
26 (The number of gift bags) x the price of each bag would cost close to $234. That would be the reasonable estimate and I hope this helps!
Slope y-intercept form is: y=mx+b
All you have to do is rearrange the equation:
2x-3y=6
2x=6+3y
2x-6=3y
now divide both sides by 3
(2x/3)-(6/3)=(3y/3)
and it becomes

x
Bonus: you can plug in any two values for x and y and you can see both equation gives the same answer!
Answer:

EXPLANATION
20 cents=10mins
customers working hrs=$4.60*10

Lets say you have 5 apples, but the you give away 3 of them.
To work how many you have left you take away.
5-3 = 2
Lets apply this with fractions now.
You have 9/7 yard, but then you give away 7/20 yard.
Now you take them away:
9/7 minus 7/20 = 131/140
Hope this helps :)
