The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$- 24 x = 48 x - 33$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-72\right) x = -33$$
Divide both parts of the equation by -72
We get the answer: x = 11/24
8*(5-3*x) = 6*(2*4*x)+7
Expand brackets in the left part
8*5-8*3*x = 6*(2*4*x)+7
Expand brackets in the right part
8*5-8*3*x = 6*2*4*x+7
Move free summands (without x)
from left part to right part, we given:
$$- 24 x = 48 x - 33$$
Move the summands with the unknown x
from the right part to the left part:
$$\left(-72\right) x = -33$$
Divide both parts of the equation by -72
x = -33 / (-72)
We get the answer: x = 11/24
