Question

PLEASE HELP!

Beth is solving this equation: 1/3 + 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.


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


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


You can assume x does not equal 0 because both sides are undefined is x = 0.


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

Answer 1

x= 0.9

step-by-step Step-by-step explanation:

LCM=3x

use the lcm to multiply each term

3x×1/3+3x×3=3x×3/x

cancel out

x+9x=9

10x=0

divide both side by the coefficient of x

10x/10=9/10

x=0.9
