17*x - 8 = 20*x - 7
17x8=20x717 x - 8 = 20 x - 7
Detail solution
Given the linear equation:
17*x-8 = 20*x-7

Move free summands (without x)
from left part to right part, we given:
17x=20x+117 x = 20 x + 1
Move the summands with the unknown x
from the right part to the left part:
3x=1- 3 x = 1
Divide both parts of the equation by -3
x = 1 / (-3)

We get the answer: x = -1/3
