Question

Why is ÷ by five a step, there did this 5 come from if its not in the inequality? ​

Answer 1

You divide by five because it's the common factor of 5 and 15 in the 4th line of work and the goal is to solve for x. The only way to get x alone in the inequality 5x>15 is to divide each side by 5. This would give you x and 3, hence the answer: x > 3

`(5x)/(5) =x\\\\(15)/(5) =3`
