The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = - \frac{3}{2}$$
Divide both parts of the equation by -8
We get the answer: x = 3/16
-8*x+(3/2) = 0
Expand brackets in the left part
-8*x+3/2 = 0
Move free summands (without x)
from left part to right part, we given:
$$- 8 x = - \frac{3}{2}$$
Divide both parts of the equation by -8
x = -3/2 / (-8)
We get the answer: x = 3/16
