Question

A restaurant sells cheeseburgers for $5.00 and French fries for $3.00. An

equation that represents the number of cheeseburgers and French fries that can

be bought for $20.00 is 5x + 3y = 20. Rearrange the equation to solve for the

number of French fries. *

Answer 1

x = (20 - 3y) / 5

Step-by-step explanation:

Let

french fires be represented by = x

cheeseburgers be represented by = y

The equation is given as;

5x + 3y = 20.

Rearrange the equation to solve for the number of French fries.

This means we are to make french fries (x) the subject of equation

5x + 3y = 20

5x = 20 - 3y

x = (20 - 3y) / 5
