We have two equations here:

#### Explanation:

$t = p - 4$
$t + p = 140$

We may replace $t$ in the second equation by $p - 4$
$p - 4 + p = 140 \to$

Now add $4$ to both sides:
$p - \cancel{4} + p + \cancel{4} = 140 + 4 \to$
$2 p = 144 \to p = 72 \to$
$t = p - 4 = 72 - 4 = 68$

Check : $t + p = 68 + 72 = 140$
