The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 3
We get the answer: x = 1
5*x-2*x+3 = 6
Looking for similar summands in the left part:
3 + 3*x = 6
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 3
x = 3 / (3)
We get the answer: x = 1
