The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{3} = \frac{x}{2} - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-5\right) x}{6} = -3$$
Divide both parts of the equation by -5/6
We get the answer: x = 18/5
3-x/3 = x/2
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{3} = \frac{x}{2} - 3$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-5\right) x}{6} = -3$$
Divide both parts of the equation by -5/6
x = -3 / (-5/6)
We get the answer: x = 18/5
