The solution
Detail solution
Given the linear equation:
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 = 8
4*x = 24+x
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 3
x = 24 / (3)
We get the answer: x = 8
