Question

How do you solve `3x - 5= 3( x - 1) + 7`?

Answer 1

This is an invalid equation with no valid solution for the value of `x` .

Explanation:

You first rearrange the equation for something to equal to x.

`3x -5 = 3(x-1) +7`
`3x = 3x - 3 + 7 + 5`
`3x = 3x + 9`

Then it is found that x is non-existent for this equation because the next step usually to solve this would be:
`0 = 9` which is invalid.
