Question

How do you solve `4(t-7)<2(t+9)`?

Answer 1

`t <23`

Explanation:

`4(t-7) < 2(t+9)" "` remove the brackets

`4t-28<2t+18" "` treat like an equation

`4t -2t < 18+28`

`2t < 46" "`isolate t so divide by 2

`t <23`

In this case we could treat the inequality exactly as an equation because it did not involve division or multiplication by a negative number.
