The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 8 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -20$$
Divide both parts of the equation by -5
We get the answer: x = 4
3*x+5 = 8*x-15
Move free summands (without x)
from left part to right part, we given:
$$3 x = 8 x - 20$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-5\right) x = -20$$
Divide both parts of the equation by -5
x = -20 / (-5)
We get the answer: x = 4
