The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$x = 5 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -28$$
Divide both parts of the equation by -4
We get the answer: x = 7
x+12 = 5*x-16
Move free summands (without x)
from left part to right part, we given:
$$x = 5 x - 28$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-4\right) x = -28$$
Divide both parts of the equation by -4
x = -28 / (-4)
We get the answer: x = 7
