What is x if 1/x + 1/3 = 1

1 1/2

Step-by-step explanation:

1/x + 1/3 = 1

First solve the left side.

LCM of x And 3 = 3x

So, divide the denominators of both fraction and multiply the results with the numerators.

We have 3+x / 3x = 1

Cross multiply

3x x 1 = 3 + x

3x = 3 + x

3x - x = 3

2x = 3

Divide both sides by 2

2x/2 = 3/2

x = 1 1/2
