The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 6 x - 63$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = -63$$
Divide both parts of the equation by -9
We get the answer: x = 7
7-3*x = 6*x-56
Move free summands (without x)
from left part to right part, we given:
$$- 3 x = 6 x - 63$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-9\right) x = -63$$
Divide both parts of the equation by -9
x = -63 / (-9)
We get the answer: x = 7
