Question

One student solved the inequality −4 > x /−7 and got 28 < x. Another student solved the inequality and got x > 28. Are they both correct? Explain.

Answer 1

Explanation:

-4 > x / -7....multiply both sides by -7, and flip the sign

-4 * -7 < = x

28 < x....or x > 28

yes, they are both the same.

28 < x ....this is saying that 28 is less then x

x > 28....this is saying that x is greater then 28

so there both saying the same thing
