solve for t. 9 + 10t = 7 + 9t + 2 t =

Explanation:

Step1: Simplify the right - hand side

First, simplify $7 + 9t+2$ to $9 + 9t$. So the equation becomes $9 + 10t=9 + 9t$.

Step2: Subtract 9t from both sides

$9 + 10t-9t=9 + 9t-9t$, which simplifies to $9 + t=9$.

Step3: Subtract 9 from both sides

$9 + t-9=9 - 9$, so $t = 0$.

Answer:

$0$
