The solution
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:
$$4 x = - x - \frac{29}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = - \frac{29}{5}$$
Divide both parts of the equation by 5
We get the answer: x = -29/25
4*x+(31/5) = (2/5)-x
Expand brackets in the left part
4*x+31/5 = (2/5)-x
Expand brackets in the right part
4*x+31/5 = 2/5-x
Move free summands (without x)
from left part to right part, we given:
$$4 x = - x - \frac{29}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = - \frac{29}{5}$$
Divide both parts of the equation by 5
x = -29/5 / (5)
We get the answer: x = -29/25
