[00:00:01]We have a simple algebra on the board, okay? 3y + 7 = 25. We are asked to find y factorial. I hope you can still remember your factorial. So, solution.

[00:00:13]We have 3y + 7 = 25. So, we're simply going to be making this 3y a subject of the formula.

[00:00:22]So, we have 3y = 25. As this 7 is crossing over here, it turns to minus.

[00:00:27]So, our 3y will be 25 - 7 will give us 18.

[00:00:35]Okay? So, our 3y is now equals to 18.

[00:00:39]So, we divide all with 3 to get our y.

[00:00:44]This into this is 1. This into 18 is 6.

[00:00:48]So, our y is now what? 6. And we are asked to find y factorial. So, it simply means 6 factorial. So, 6 factorial is 6 * 5 * 4 * 3 * 2 * 1. If you don't know your factorial, please consult my old videos. So, when you multiply all these numbers, you'll be having 720.

[00:01:15]So, this is your final answer.
