16 - 2t = 5t + 9

What number does t represent? I'm bored

Try not to be bored. You can take the attitude that you actually like math, and that you will some day actually be a MathGenius.

t represents an unknown quantity defined by the equation 16 - 2t = 5t + 9.

To find this value, do the following: Add 2t to both sides, and then subtract 9 from both sides. You'll end up with 7t = 7, which yields t = 1.

We call this the "solution" of the equation given.
