Solve for tt in the equation 9=t+4s-9=t+4s. Options: a) t=94st=-9-4s, b) t=9+s4t=\frac{-9+s}{4}, c) t=9s4t=\frac{-9-s}{4}, d) t=9s4t=-9-s-4.

STEP 1

Assumptions
1. We are given the equation 9=t+4s-9 = t + 4s.
2. We need to solve for tt in terms of ss.

STEP 2

To isolate tt on one side of the equation, we need to move the term 4s4s to the other side. We do this by subtracting 4s4s from both sides of the equation.
94s=t+4s4s-9 - 4s = t + 4s - 4s

STEP 3

Simplify both sides of the equation by combining like terms.
94s=t-9 - 4s = t

STEP 4

We have now isolated tt on one side of the equation. The equation 94s=t-9 - 4s = t matches option (a) t=94st = -9 - 4s.
Therefore, the correct answer is: t=94st = -9 - 4s
