Write the equations: Two of Julie’s textbooks are a total of $65. The difference in price between the two books is $9. What is the cost of each book?
Let ___ = _____________
Let ___=______________
Let x = the cost of the first textbook
Let y = the cost of the second textbook
Based on the given information, we can set up the following equations:
Equation 1: x + y = 65 (the total cost of the two textbooks is $65)
Equation 2: x - y = 9 (the difference in price between the two books is $9)
Let x = the cost of the first textbook
Let y = the cost of the second textbook
From the given information, we can create two equations to represent the situation:
Equation 1: "Two of Julie’s textbooks are a total of $65"
x + y = 65
Equation 2: "The difference in price between the two books is $9"
x - y = 9
Now, we can solve this system of equations to find the values of x and y.
Let x = the cost of one textbook
Let y = the cost of the other textbook
Given:
x + y = $65
x - y = $9
These are the two equations representing the given information.
