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 11
We get the answer: x = 4
9*x+4 = 48-2*x
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 11
x = 44 / (11)
We get the answer: x = 4
