The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 20 x + 82$$
Move the summands with the unknown x
from the right part to the left part:
$$- 10 x = 82$$
Divide both parts of the equation by -10
We get the answer: x = -41/5
10*x-8 = 20*x+74
Move free summands (without x)
from left part to right part, we given:
$$10 x = 20 x + 82$$
Move the summands with the unknown x
from the right part to the left part:
$$- 10 x = 82$$
Divide both parts of the equation by -10
x = 82 / (-10)
We get the answer: x = -41/5
