The correct answer would be 5t + 3
Why?
You first look at the same terms.
For this equation they are 7t and 2t
Since 2t is behind the minus sign, you will use the subtraction property.
7t - 2t = 5t.
Then combine the equation with the answer.
5t + 3
Nothing else can be done with this equation.
Your answer is 5t + 3
Hope this helped! :D
