Final Answer: [tex]t = 9[/tex]
Steps/Reasons/Explanation:
Question: Solve for [tex]t[/tex]. [tex]-t=9(t-10)[/tex].
Step 1: Expand.
[tex]-t = 9t - 90[/tex]
Step 2: Subtract [tex]9t[/tex] from both sides.
[tex]-t - 9t = -90[/tex]
Step 3: Simplify [tex]-t - 9t[/tex] to [tex]-10t[/tex].
[tex]-10t = -90[/tex]
Step 4: Divide both sides by [tex]-10[/tex].
[tex]t = \frac{-90}{-10}[/tex]
Step 5: Two negatives make a positive.
[tex]t = \frac{90}{10}[/tex]
Step 6: Simplify [tex]\frac{90}{10}[/tex] to [tex]9[/tex].
[tex]t = 9[/tex]
