Answer:
[tex]t=\frac{b}{b+a}[/tex]
Step-by-step explanation:
we have
[tex]t+\frac{at}{b}=1[/tex]
Solve for t
That means ----> Isolate the variable t
Multiply by b both sides to remove the fraction
[tex]bt+at=b[/tex]
Factor the variable t in the left side
[tex]t[b+a]=b[/tex]
Divide by (b+a) both sides
[tex]t=\frac{b}{b+a}[/tex]
