remember, you can do anything to an euation as long as you do it to both sides

4t+9=-8t-13
add 8t to both sides
12t+9=-13
minus 9 from both sides
12t=-22
divide both sides by 12
[tex]t=\frac{-22}{12}[/tex]
[tex]t=\frac{-11}{6}[/tex]

Hi!

4t+9=-8t-13

To solve, first add 13 to both sides.
4t+9+13=-8t-13+13
4t+22=-8t
Subtract 4 from both sides
4t-4+22=-8t-4
22=-12t
Divide by -12 on both sides
22/12=-12t/-12
22/-12 = t
Which can be simplified to...
-11/6 = t

The answer is t = -11/6

Hope this helps! :)
