The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 72 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 72$$
Divide both parts of the equation by -7
We get the answer: x = -72/7
-8*x-8 = 64-x
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = 72 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-7\right) x = 72$$
Divide both parts of the equation by -7
x = 72 / (-7)
We get the answer: x = -72/7
