Question

Solve for x.

x - 1/12 = 7/2

The answer is x = 43.

Answer 1

There are a few ways of doing it. I would first multiply the whole equation by 12 because I don't like fractions.

Answer 2

Oh, I know how to do it, I just need my answer to be checked. My answer is 43 = x. That is correct, right?

Answer 3

@thomas5267 ^

Answer 4

I am afraid that the answer is wrong. 43-1/12=515/12

Answer 5

No, I am positive that it is correct.

Answer 6

43 - 1 = 42

42/12 = 7/2

Answer 7

The two answers are equal.

Answer 8

Oh! So it is \(\frac{x-1}{12}=\frac{7}{2}\) not \(x-\frac{1}{12}=\frac{7}{2}\)?

Answer 9

in order to solve for 'x' you need to do the inverse operations...

Answer 10

so instead of - 1/12 you add 1/12 to both sides

Answer 11

Yeah! Sorry if it was confusing! @thomas5267

Answer 12

Then yes your answer looks right!

Answer 13

OH, ok I thought that looked too easy, I get it :P

Answer 14

@ccswims I actaully just multiplied 12 by 7, then I divided 84 by 2, to get 42, which is 1 less than 43. :)
