The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = x + 7$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 7$$
Divide both parts of the equation by -3
We get the answer: x = -7/3
20-2*x = 27+x
Move free summands (without x)
from left part to right part, we given:
$$- 2 x = x + 7$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-3\right) x = 7$$
Divide both parts of the equation by -3
x = 7 / (-3)
We get the answer: x = -7/3
