Hey there!☺

Answer:\boxed{t=2}

Explanation:

5t-9=-3t+7

Let's start by adding 3t to both sides of the equation.

5t-9+3t=-3t+7+3t\\8t-9=7

Now let's add 9 to both sides of the equation.

8t-9+9=7+9\\8t=16

Now let's divide both sides by 8.

\frac{8t}{8} =\frac{16}{8}

Now let's simplify 16/8.

16/8=2

t=2

Hope this helps!

LiRa [457]

If you are looking to write an inequality equation that models this situation, then the answer would be: 5+2x\leq 27.  The "at most" signals to use the less than or equal to sign.
