Final Answer:
t = 9

Steps/Reasons/Explanation:

Question: Solve for
t.
-t=9(t-10).

Step 1: Expand.


-t = 9t - 90

Step 2: Subtract
9t from both sides.


-t - 9t = -90

Step 3: Simplify
-t - 9t to
-10t.


-10t = -90

Step 4: Divide both sides by
-10.


t = (-90)/(-10)

Step 5: Two negatives make a positive.


t = (90)/(10)

Step 6: Simplify
(90)/(10) to
9.


t = 9
