Answer:
x=9
Step-by-step explanation:3x-5+x=31
3x+x=31+5
4x=36
x=36/4
x=9
The numerator factors as (t-8)(t+4), so the whole thing is (t-8)(t+4)/(t-8). Now we can cancel the t-8 AS LONG as t isn't equal to 8, otherwise, we are canceling a zero from both numerator and denominator which is invalid. What is left is t+4.
So your choice was right.
