Question

Use the digits 1-9 at lost one time each to make the equation true and give the solution

Answer 1

`2-3x=6x-7\\x=1`

(There are a lot more combinations tho. Read more!)

Explanation:

The first thing to notice is that the answer has to be a whole number and that there are only 5 spaces.

Another thing to notice is that one of the x's is negative.

So the easiest thing is to set
`x=1`.

The we can work backwards. There are multiple solutions that we can use. But any combination that adds to the same number will work.

Such as:

`2-3x=6x-7\\x=1`

or

`2-5x=3x-6\\x=1`

And so on.
