2*x 19 13 4*x --- + -- = -- - --- 5 5 5 5
$$\frac{2 x}{5} + \frac{19}{5} = \frac{13}{5} - \frac{4 x}{5}$$
Detail solution
Given the linear equation:
Expand brackets in the left part
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{5} = - \frac{4 x}{5} - \frac{6}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{6 x}{5} = - \frac{6}{5}$$
Divide both parts of the equation by 6/5
We get the answer: x = -1
(2/5)*x+(19/5) = (13/5)-(4/5)*x
Expand brackets in the left part
2/5x+19/5 = (13/5)-(4/5)*x
Expand brackets in the right part
2/5x+19/5 = 13/5-4/5x
Move free summands (without x)
from left part to right part, we given:
$$\frac{2 x}{5} = - \frac{4 x}{5} - \frac{6}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$\frac{6 x}{5} = - \frac{6}{5}$$
Divide both parts of the equation by 6/5
x = -6/5 / (6/5)
We get the answer: x = -1
