The solution

You have entered [src]
-x = 6 - 7*(x - 3)
x=67(x3)- x = 6 - 7 \left(x - 3\right)
Detail solution
Given the linear equation:
-x = 6-7*(x-3)

Expand brackets in the right part
-x = 6-7*x+7*3

Looking for similar summands in the right part:
-x = 27 - 7*x

Move the summands with the unknown x
from the right part to the left part:
6x=276 x = 27
Divide both parts of the equation by 6
x = 27 / (6)

We get the answer: x = 9/2
