Answer:
t = 9
Step-by-step explanation:
<em>-t = 9(t - 10)</em>
First, distribute the 9.
<em>-t = 9t - 90</em>
Next, add subtract 9t from both sides.
<em>(-t) - 9t = (9t - 90) - 9t</em>
<em>-10t = -90</em>
Divide both sides by -10. When you divide a negative by another negative, they cancel each other out.
<em>(-10t)/-10 = (-90)/(-10)</em>
<em>t = 9</em>
There you go. Let me know if you have questions
