Answer 1

.1

Answer 2

0.9t/t=0.9, 0.9-1= 0.1

Answer 3

Subtract 0.9t from both sides, and subtract 1 from both sides, so you get:
0.9t = 1 + t
0.9t - 0.9t - 1 = 1 + t -0.9t - 1
and simplify...
-1 = 0.1t
multiplyt both sides by 10 to get...
-10 = t

Answer 4

0.9t=1+t
Transpose t from RHS to LHS

Answer 5

we will get: 0.9t -t =1

Answer 6

take t common
t (0.9-1)=1

Answer 7

solve for t
