Tip: do not click on the links, it’s a scam. Also an easier way to get answers quicker is post the picture and then briefly explain the post and not the entire question. :) I hope that helps. Have a great day!
~Hello There!~

Rearrange for s

After 8 years, the new equation would be:

Cross multiply

Subtract 8

Substitute old equation

Solve to get m as 16.

Hope This Helps You!
Good Luck :)
Have A Great Day ^_^
