Y= 12 - x
27 + 3( 12 - x ) = 2x
The best way to approach a word problem like this
is to break it down into pieces, so we can understand it fully.
In this problem, we have a number, which we don't know.
We can use any variable to represent it.
So let's use the variable <em>n</em> to represent it.
"Two less than three times a number" means 3n - 2.
A common mistake is for students to put 2 - 3n.
However, the word "less than" switches the order around.
So we have 3n - 2 = 19.
Solving from here, we add 2 to both sides to get 3n = 21.
Now divide both sides of the equation by 3 and we have n = 7.
So the number is 7.

Vertical line has no slope. so only look at the x value. x=-4.
Answer:
We need the hourly rate for renting the bicycle. Assuming that the rate is Rb, we can state: Cb = AED5.00 + Rb*x for renting a bicycle for x hours
Step-by-step explanation:
Assuming that the rate for renting a bicycle is Rb, the cost (in AED), Cb (in AED/hr), of a bicycle rental for x hours would be:
Cb = AED5.99 + Rb*x
Assuming the transportation fee applies, the cost of renting a canoe for 6 hours would be: AED = 5 + 2.00*6 , or AED17 for 6 hours
