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:
$$- \frac{x}{2} = x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-3\right) x}{2} = -9$$
Divide both parts of the equation by -3/2
We get the answer: x = 6
-(1/2)*x-4 = 1*x-13
Expand brackets in the left part
-1/2x-4 = 1*x-13
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{2} = x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-3\right) x}{2} = -9$$
Divide both parts of the equation by -3/2
x = -9 / (-3/2)
We get the answer: x = 6
