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:
$$x = 4$$
We get the answer: x = 4
3*x-2*x+4 = 8
Looking for similar summands in the left part:
4 + x = 8
Move free summands (without x)
from left part to right part, we given:
$$x = 4$$
We get the answer: x = 4
