Answer:

$(t,50-t) = \{(10,40),(20,30),(25,25)\}$

Step-by-step explanation:

Given

$Expression: 50 - t$

Required

Evaluate when:

$t = \{10,20,25\}$

When $t =10.$

The expression is:

$50 - t = 50 - 10$

$50 - t = 40$

When t = 20

The expression is:

$50 - t = 50 - 20$

$50 - t =30$

When $t = 25$

The expression is:

$50 - t = 50 - 25$

$50 - t =25$

The result is:

$(t,50-t) = \{(10,40),(20,30),(25,25)\}$
