Answer:
Step-by-step explanation:
Solve by Substitution :
// Solve equation [2] for the variable y
[2] y = -x + 5
// Plug this in for variable y in equation [1]
[1] x - 2•(-x +5) = 8
[1] 3x = 18
// Solve equation [1] for the variable x
[1] 3x = 18
[1] x = 6
// By now we know this much :
x = 6
y = -x+5
// Use the x value to solve for y
y = -(6)+5 = -1
Solution :
Divide the price by the number of ounces.
=$1.99 ÷ 15 ounces
=$0.13
The price per ounce of the 15 ounce can is $0.13.
Hope this helps! :)
