I’m stuck with this question :(

Answer:
The same number was not added to both sides.
Step-by-step explanation:
Given:
t - 8 = 65
in the next step it states something wrong, because it should have been this:
t - 8 = 65
add +8 left and right of the = sign.
t - 8 + 8 = 65 + 8
t + 0 = 73
t = 73
So the error made what's that
The same number was not added to both sides.
Answer:
The same number was not added to both sides

t - 8+8 = 65+8
The student added 8 on one side and 65 on the other
t = 73
