let the cost of pizza be x

let the cost of the bottle be y

Theo buys a slice of pizza and a water bottle for $3 therefore, the equation becomes

Step 2

Ralph buys 3 slices of pizza 3x and 2 bottles of water

solving equation 1 and equation 2 to get the values of x and y substitute the value of

Step 3

putting the value of y in equation (1) we get

therefore, the cost of the pizza is
