The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 4 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -14$$
Divide both parts of the equation by -1
We get the answer: x = 14
3*x+6 = 4*x-8
Move free summands (without x)
from left part to right part, we given:
$$3 x = 4 x - 14$$
Move the summands with the unknown x
from the right part to the left part:
$$- x = -14$$
Divide both parts of the equation by -1
x = -14 / (-1)
We get the answer: x = 14
