Question

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

Answer 1

Answer: x + (x+5) = 77

Explanation: the last equation option wasn’t written right on the question

Answer 2

If the smaller number is x,the greater one is x+5
so x+ x + 5 = 77 
    2x= 77 - 5
    2x = 72
      x = 36
so, none of the equations are right
