Answer:
Solving equations by substitution is exactly as it says it is, you will simply substitute.
In your example: y=2x+2, y=0
You will plug 0 in for y
Your equation will now look like 0=2x+2, now you are going to solve it like a normal equation, getting x by itself
0=2x+2 (first you want to minus 2 from each side)
-2=2x (now you are going to divide each side by 2)
-1=x
x=-1

Step-by-step explanation:
Price yesterday = $180
Price today = $207
Increase in price = $(207 - 180)
=> $27
Percent increase =
Increase / Price of yesterday

=> 3 / 2 * 10
=> 30 / 2
=> 15
15%
Therefore, the rise in the price of the item = 15%
