Answer:
Step-by-step explanation:
To get equivalent expressions, if you are adding or subtracting, the number and letter you get on the left must be the same as the one on the right.
In B. The answer is incorrect because 4t is minus on the left. The letters are different, so 4t must remain minus. Not B
In C the numbers will combine when you add. If they are the same,, they remain the same. They do not become powers the answer for C is 10s. So C is not correct.
In D you are indicating that 6 is multiplied by 4s. You can only multiply 6 and 4. They don't add. Not D
A is correct.

A quotient is the answer of a division.
Let
x
be the unknown number.
The quotient of
x
and
−
5
is
(
x
−
5
)
.
"Increased by one" means add
1
, so now we have
(
x
−
5
)
+
