The solution
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:
$$3 x = 4 x - 14$$
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+2) = 4*(x-2)
Expand brackets in the left part
3*x+3*2 = 4*(x-2)
Expand brackets in the right part
3*x+3*2 = 4*x-4*2
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
