Answer:

Step-by-step explanation:
Hello there!
The first thing we want to do is find the least common denominator which would be 20
so we multiply the denominator and numerator of the fractions on the left side by 4
3x4=12
5x4=20 -12/20x
1x4=4
5x4=20 so now we would have

once again we want to isolate the variable using inverse operations
to get rid of the 4/20 we subtract each side by 4/20

now we have

now we want to get rid of the -12/20
to do so we divide each side by -12/20 (or -.6 as a decimal to make it easier)

REMEMBER flip the equality sign
we're left with

Answer:
C
Step-by-step explanation:
First, factor the original expression:

As we can see, D is the same as above. Eliminate D.
Go through each of the answer choices.
A:

This is equivalent to what we factored. Eliminate A.
B:

This is again equivalent to what we factored. Eliminate B.
C:

This cannot be simplified and it is not equivalent to what we have previously. C is not the equivalent expression.
The answer should be 8x+5
