25t means "25 times t" where t is some unknown number. It is a placeholder for a number.

To find what the number is, we undo what is happening to t. So we divide both sides by 25 to undo the operation "multiply by 25"

----------

25*t = 1125

25*t/25 = 1125/25 divide both sides by 25

t = 45

---------

<h3>Answer: 45</h3>

As a check, we can plug t = 45 into the equation and we should get the same value on both sides

25*t = 1125

25*45 = 1125 replace every t with 45

1125 = 1125 the answer is confirmed
