$t <23$

$4(t-7) < 2(t+9)" "$ 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.
