Answer:
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
