Learn with an example

Which of the following is a solution to the inequality below?

^–5

^–1

^–6

^–7

Go through the answer choices one by one.

Plug u = ^–5 into the inequality.

^–5

Plug in u = ^-5

It is false that ^–5 < ^–5. So, u = ^–5 is not a solution.

Plug u = ^–1 into the inequality.

^–5

^–1

Plug in u = ^-1

It is true that ^–5 < ^–1. So, u = ^–1 is a solution.

Plug u = ^–6 into the inequality.

^–5

^–6

Plug in u = ^-6

It is false that ^–5 < ^–6. So, u = ^–6 is not a solution.

Plug u = ^–7 into the inequality.

^–5

^–7

Plug in u = ^-7

It is false that ^–5 < ^–7. So, u = ^–7 is not a solution.

Only u = ^–1 is a solution.
