The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = x + 21$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 21$$
Divide both parts of the equation by 3
We get the answer: x = 7
4*x-13 = 8+x
Move free summands (without x)
from left part to right part, we given:
$$4 x = x + 21$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 21$$
Divide both parts of the equation by 3
x = 21 / (3)
We get the answer: x = 7
