Question

For what value of \(x\) is \(\Large\frac{ 2x }{ 3x-1 }\) undefined?

Answer 1

its undefined when the denominator is 0

Answer 2

Remove the parentheses around the expression 3x−1.
3x−1=0
Since −1 does not contain the variable to solve for, move it to the right hand side of the equation by adding 1 to both sides.
3x=1
Divide each term in the equation by 3.
3x/3=1/3
Cancel 3 in the numerator and denominator.
( 3 x)/( 3 )=1/3
Divide x by 1 to get x.
x=1/3
