The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{5} = \frac{3 x}{2} + 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-17\right) x}{10} = 5$$
Divide both parts of the equation by -17/10
We get the answer: x = -50/17
3-x/5 = 8+3*x/2
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{5} = \frac{3 x}{2} + 5$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{\left(-17\right) x}{10} = 5$$
Divide both parts of the equation by -17/10
x = 5 / (-17/10)
We get the answer: x = -50/17
