The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Move free summands (without x)
from left part to right part, we given:
$$4 x = 2 x + \frac{8}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = \frac{8}{5}$$
Divide both parts of the equation by 2
We get the answer: x = 4/5
4*x-1 = 2*(x+(3/10))
Expand brackets in the right part
4*x-1 = 2*x+2*3/10)
Move free summands (without x)
from left part to right part, we given:
$$4 x = 2 x + \frac{8}{5}$$
Move the summands with the unknown x
from the right part to the left part:
$$2 x = \frac{8}{5}$$
Divide both parts of the equation by 2
x = 8/5 / (2)
We get the answer: x = 4/5
