We have to substitute the pairs in the inequality and find which of them satisfies it
1) $2\left(2\right)-3\left(0\right)=4<5$ is true (satisfies)
2) $2\left(1\right)-3\left(-1\right)$
$=2+3=5<5$ is false (doesn't satisfy)
3) $2\left(0\right)-3\left(0\right)=0<5$ is true (satisfies)
4) $2\left(2\right)-3\left(4\right)$
$=4-12=-8<5$ is true (satisfies)
