The solution
Detail solution
Given the linear equation:
Move free summands (without z)
from left part to right part, we given:
$$0 = 3000 z - 24000$$
Move the summands with the unknown z
from the right part to the left part:
$$\left(-3000\right) z = -24000$$
Divide both parts of the equation by -3000
We get the answer: z = 8
24000 = 3000*z
Move free summands (without z)
from left part to right part, we given:
$$0 = 3000 z - 24000$$
Move the summands with the unknown z
from the right part to the left part:
$$\left(-3000\right) z = -24000$$
Divide both parts of the equation by -3000
z = -24000 / (-3000)
We get the answer: z = 8
