How do linear relation equations work?
My girlfriend is working on her maths and she's come up to linear elationships, how are we supposed to work them out.
Examples
5x + 8 = 2
-15=3-6x
I need to know how to do it, not the answers.

5x + 8 = 2
Subtract 8 from both sides:
5x = -6
Divide by sides by 5:
x = -6/5 = -1.2
-15 = 3 - 6x
Subtract 3 from both sides:
-18 = -6x
Divide both sides by -6 and switch sides:
x = 3
