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 4
We get the answer: x = 7
3*x = 28-x
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 4
x = 28 / (4)
We get the answer: x = 7
