AWARDING BRAINLIEST!! 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 incorrect? Select all that apply.

Question 1 options:

After multiplying both sides by x you need to subtract 1 from both sides

You can assume x ≠ 0 because both sides are undefined if x = 0.

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

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

1. After multiplying both sides by x you need to subtract 1 from both sides

2. You can assume x ≠ 0 because both sides are undefined if x = 0.

Which of the options shows the validity of Beth's action

The first option answers the question and the reason is as follows;

Multiply both sides by x

Open the bracket

As stated in option 1; Subtract 1 from both sides

Divide both sides by 2

Another correct option is the option 2

Because the expression is undefined if x = 0

See Proof by substituting 0 for x

Division by 0 is undefined.

Hence, option 2 is also correct

The other options (3 and 4) are incorrect

y=sec x is the correct answer
