The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$10 x = 4 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = 4$$
Divide both parts of the equation by 6
We get the answer: x = 2/3
10*x-11 = 4*x-7
Move free summands (without x)
from left part to right part, we given:
$$10 x = 4 x + 4$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = 4$$
Divide both parts of the equation by 6
x = 4 / (6)
We get the answer: x = 2/3
