3x / 5x+2

a. - 2/5
b. - 1 / 5
c. 1/5
d. 2/5

please help me, last question on my homework :)

Answer 1

idk :>

Answer 2

Non-permissibale replacement is when the denominator is equal to zero so which would cause that to happen?

Answer 3

pellet these fractions as answers make it hard -.-

Answer 4

It makes it easier if we just focus on the denominator.

Answer 5

okay let me see..

Answer 6

We can see that our 2 does not depend on anything so we must find an x value for which it makes the other side cancel out the 2

Answer 7

so with that in mind you already know it will be a negative value

Answer 8

so C and D are out. thank you for that.

Answer 9

You also know that it has to be the same number as 2 to cancel it out just negative so you want 5x to turn into -2
