The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 3
We get the answer: x = -5
20*x+7 = 17*x-8
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 3
x = -15 / (3)
We get the answer: x = -5
