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 statement makes a correct argument, or shows that it is incorrect? select all that apply
A. you can assume x ≠ 0 because both sides are undefined if x = 0
B. after multiplying both sides by x you need to subtract 1 from both sides
C. you cannot multiply both sides by x because you do not know what x is.
D. the equation is not linear, so you cannot use the methods normally used for solving linear equations.
