i will replace it with any figure, you can replace it wit your given data and you will get the solution.
A local hamburger shop sold a combined total of 593 hamburgers and cheeseburgers on Thursday
There were 57 fewer cheeseburgers sold than hamburgers
How many hamburgers were sold on thursday
Let h be the number of hamburgers and c be the number of cheeseburgers.
Using this information we can set up two equation as:
![h+c=593\\c=h-57](https://img.qammunity.org/2021/formulas/mathematics/high-school/kfjgvuz33jr9ndhvns0cpko0g6oj1vc4n1.png)
Now we need to solve these two equations to get the value of number of hamburgers. For that we use substitution method as shown below:
![h+h-57=593\\2h-57=593\\2h=650\\h=325](https://img.qammunity.org/2021/formulas/mathematics/high-school/bni6xanzr9z9fobtpim0gi6ttgy1hupdle.png)
Therefore, the number of hamburgers sold on Thursday were 325.
