The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 9 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-16\right) x = -8$$
Divide both parts of the equation by -16
We get the answer: x = 1/2
-7*x+8 = 9*x
Move free summands (without x)
from left part to right part, we given:
$$- 7 x = 9 x - 8$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-16\right) x = -8$$
Divide both parts of the equation by -16
x = -8 / (-16)
We get the answer: x = 1/2
