Question

For which value of x will the fraction 7/2x-6 be undefined?

HOW TO DO THIS ?

Answer 1

A fraction is undefined if its denominator is zero, so set
2x-6 = 0
2x=6
x = 3

So x = 3 makes the fraction undefined.

Answer 2

Any fraction is undefined when the denominator is equal to zero.

In this problem the denominator is 2x-6.

In order to find what value of x is needed to make the denominator zero, set it equal to x and solve.

2x-6=o

2x=6

x=3

Therefore, this fraction is undefined (or has a denominator of zero) when x is equal to 3.

Answer 3
