Question

He sum of two numbers is 60. The greater number is 6 more than the smaller number. Which equation can be used to solve for the smaller number?

x + (x + 6) = 60
x − (x + 6) = 60
x(x + 6) = 60
x(x− 6) = 60

Answer 1

x+(x+6)=60

Since the greater number is six more than the smaller number, the variable value will be of the smaller number. And since the bigger number is six more than the smaller number, it needs to be in parantheses as x plus six. But, since the value of both the numbers is sixty, the equation will finally become x+(x+6)=60
