2*(x + 6/5) = -- - x
10
$$2 \left(x + \frac{6}{5}\right) = \frac{27}{10} - x$$
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:
$$2 x = \frac{3}{10} - x$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = \frac{3}{10}$$
Divide both parts of the equation by 3
We get the answer: x = 1/10
2*(x+(6/5)) = (27/10)-x
Expand brackets in the left part
2*x+2*6/5) = (27/10)-x
Expand brackets in the right part
2*x+2*6/5) = 27/10-x
Move free summands (without x)
from left part to right part, we given:
$$2 x = \frac{3}{10} - x$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = \frac{3}{10}$$
Divide both parts of the equation by 3
x = 3/10 / (3)
We get the answer: x = 1/10
