Beth is solving this equation: 1/x + 3 =3/x she says "I can multiply both sides by X and get the linear equation 1 + 3x = 3 whose solution is x = 2/3 ."
which of the following statements makes this a correct argument, or shows that it is in correct? Select all that apply.

a. you cannot multiply both sides by x because you do not know what x is.

b. you can assume x = 0 because both sides are undefined if x = 0

c. after multiplying both sides by X you need to subtract 1 from both sides.

d. the equation is not linear, so you cannot use the methods normally used for solving linear equations.

a. you cannot multiply both sides by x because you do not know what x is.

Step-by-step explanation:

Given:

Required

Select which of the option that applies

Considering (a):

A is incorrect:

Because: Multiplying both sides by x has nothing to do with whether the value of x is known or not

Considering (b):

B is incorrect:

Substitute 0 for x in the given expression

Both sides of the equation are undefined

However, you cannot assume x to be 0

Considering (c):

C is correct:

Start by multiplying both sides by x

Then, subtract 1 from both sides

Divide through by 3

Considering (d):

D is incorrect;

Because, the equation is linear
