2t - 32t−3

Here's how I did it:

Explanation:

5t - 3(1+t)5t−3(1+t)

The first thing we want to do is distribute (multiply) the -3−3 to everything in the parenthesis:
-3 * 1 = -3−3⋅1=−3
-3 * t = -3t−3⋅t=−3t

And when we combine them we get -3 - 3t−3−3t. Now the expression is:
5t - 3 - 3t5t−3−3t

Now we do 5t-3t5t−3t:
2t - 32t−3 (final simplified answer)

Your answer is 2t - 3 2t−3

Explanation:

Firstly open up the bracket - 3(1 +t ) −3(1+t) this is equal to -3 -3t −3−3t. I am sure you noticed the sign change this is because minus times plus equals minus. Your equation know is 5t -3 -3t 5t−3−3t which is then 5t -3t - 3 5t−3t−3. The simplification is 2t - 3 2t−3. Hope this helps
