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 -5
We get the answer: x = 5
7-2*x = 3*x-18
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 -5
x = -25 / (-5)
We get the answer: x = 5
