Question

How would you solve 1/3 + 1/4 = 1/x?
I got 12/7 but I'm not sure if that's the way it's supposed to be answered?

Answer 1

It is correct.

Answer 2

Multiply both sides by 12 which eliminates the denominators.

Answer 3

12/7

Answer 4

sorry for it

Answer 5

\(\huge \frac{1}{3}+ \frac{1}{4}= \frac{4+3}{4*3}= \frac{7}{12}\)
so x = 12/7

Answer 6

I made 12x the common denominator which made the numerators 4x + 3x = 12 and then I added 4x + 3x to get 7x and divided 7 on both sides of the equation.

Answer 7

that is also correct

Answer 8

okay. thank you!
