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?
please answer quick i will mark you brainliest if correct!

x(x − 5) = 77
x(x + 5) = 77
x − (x + 5) = 77
x + (x + 5) = 77

Answer 1

Answer:

Correct answer is option b

Answer 2

Step by step explanation:

Let any two numbers be x and y respectively

Given that greater number is 5 more than the smaller number

Let us take y as greater number and x as smaller number

So, y = 5 + x

Sum of two numbers is 77

x + y = 77

x + (x + 5) = 77 ( since y = x + 5)

x + x + 5 = 77

2x + 5 = 77

2x = 77 - 5

2x = 72

x = 72/2

x = 36

y = 36 + 5 = 41

So option d) is the correct answer
x + (x + 5)
