The sum of two numbers is 77. The greater number is 5 more than the smaller number. Which equation can be used to solve for the smaller number?
x(x − 5) = 77
x(x + 5) = 77
x − (x + 5) = 77
x + (x + 5) = 77

Best ResponseYou've already chosen the best response.1Correct. Now we know the two numbers are x and x + 5. We are told the sum of the numbers is 77. How do you express the sum of x and x + 5?

Best ResponseYou've already chosen the best response.1Exactly. Just one step left to do. We are told the sum is 77. That means that sum you just wrote equals 77. Can you write that now?
