Answer: The answer to this question is t=9
Step-by-step explanation: This is the linear equation, to solve it we have to simplify the like terms.
-t= 9(t-10)
-t=9t-90
-10t=-90
t= 9
On the right hand side multiply through out by 9 and move 9t to the other side it will change side.
Then divide both sides by -10
