x: Represents the amount of small popcorn tubs
y: Represents the amount of large popcorn tubs
According to the data we have to:
(Spending all the money in your wallet)
(Buying 7 popcorn tubs)
From the second equation we have:
Substituting in the first equation:

Answer:
(1,3) and (4,6)
Step-by-step explanation:
<u>----Solve by substitution---</u>
Add 4x to both sides
Subtract 2 from both sides
Subtract 5x from both sides
x^2-5x+4 = 0
Factor , = (x-4)(x-1)
First variable : x = 1 and x = 4
-------------------------------
<u>Substitute</u> 1 for x in the 2nd equation
y=(1)+2 = 3
First answer is (1,3)
---------------------------------
<u>Substitute</u> 4 for x in the 1st equation
4^2-4(4)+6 = 6
Second answer: (4,6)
