The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$5 x = x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 28$$
Divide both parts of the equation by 4
We get the answer: x = 7
5*(x-4) = x+8
Expand brackets in the left part
5*x-5*4 = x+8
Move free summands (without x)
from left part to right part, we given:
$$5 x = x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 28$$
Divide both parts of the equation by 4
x = 28 / (4)
We get the answer: x = 7
