I'm going to assume that the equation is where the 't' is not in the denominator
If that assumption is correct, then we do two things to solve for t. First, we multiply both sides by 16. This undoes the division of 16 on the left side
-------------------------------
Then we divide both sides by 5 to undo the multiplication of 5 (note: 5t means 5*t or "5 times t")
-------------------------------
So here's what all the steps look like:
note: -144/5 converts to the decimal value of -28.8 so t = -144/5 is the same as t = -28.8
So first we have to find the blue line. y=mx+b is the equation. For slope it is 0--1 which is 1 and 1-0 which is 1 so the slope is just one or x now we need to find the y intercept which is just -1. So y<(is less than)x-1! Hope this helps :)
