@jdoe0001

Answer 5

-3t

Answer 6

thx

Answer 7

but then its -2t = -a

Answer 8

so plus 2!

Answer 9

\(\bf t = \cfrac{1-a}{3}\\ \quad \\
\textit{multiplying both sides by }-3\\
-3t = -\cancel{3}\times \cfrac{1-a}{\cancel{3}}\implies -3t = -(1-a)\implies -3t = a-1\\ \quad \\
\textit{adding to both sides }1\\
-3t+1 = a\cancel{-1+1}\)
