2*(19 - x) 3*x 12*19
---------- + --- = -----
3 5 19
$$\frac{3 x}{5} + \frac{2 \left(19 - x\right)}{3} = \frac{12 \cdot 19}{19}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{15} = - \frac{2}{3}$$
Divide both parts of the equation by -1/15
We get the answer: x = 10
2/3*(19-x)+3/5*x = 12/19*19
Expand brackets in the left part
2/3*19-2/3*x+3/5*x = 12/19*19
Looking for similar summands in the left part:
38/3 - x/15 = 12/19*19
Move free summands (without x)
from left part to right part, we given:
$$- \frac{x}{15} = - \frac{2}{3}$$
Divide both parts of the equation by -1/15
x = -2/3 / (-1/15)
We get the answer: x = 10
