The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$13 x = 6 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -14$$
Divide both parts of the equation by 7
We get the answer: x = -2
13*x+10 = 6*x-4
Move free summands (without x)
from left part to right part, we given:
$$13 x = 6 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -14$$
Divide both parts of the equation by 7
x = -14 / (7)
We get the answer: x = -2
