The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without x)
from left part to right part, we given:
$$4 x = x + 15$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 15$$
Divide both parts of the equation by 3
We get the answer: x = 5
4*(x-6) = x-9
Expand brackets in the left part
4*x-4*6 = x-9
Move free summands (without x)
from left part to right part, we given:
$$4 x = x + 15$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = 15$$
Divide both parts of the equation by 3
x = 15 / (3)
We get the answer: x = 5
