Each pizza cost $ 12.65
<h3>What is an Equation ?</h3>
An Equation is used in determination of unknown variables in an expression .
It is given that
Brian ordered 3 large cheese pizzas and a salad.
The salad cost $4.95
Total amount spend = $47.60
Tip = $5
The amount spend in food is $ 47.60-5
= $42.60
Let the price of Pizza is x then the equation that can be formed to determine the price of pizza is
3x + salad = 42.60
3x + 4.95 = 42.60
3x = 37.65
x = $12.65
Therefore each pizza cost $ 12.65

Given that the cost of b burgers and h hot dogs is given by 3.25b + 2h.
Therefore, the cost of 4 burgers and 6 hot dogs is given by 3.25(4) + 2(6) = 13 + 12 = $25.
Answer:
The solution is x =2 for the given equation 
Step-by-step explanation:
We need to find the solution for x in the given equation.
Solving:
Subtract 
from both sides
Taking square on both sides
Putting values and solving
Verifying the solution by putting values of x in given equation
Putting x=18
So, x=18 is not solution o given equation.
Putting x = 2
So, x=2 satisfies the equation
The solution is x =2 for the given equation
