The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$8 x = 4 x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 28$$
Divide both parts of the equation by 4
We get the answer: x = 7
8*x-18 = 6*x-2*(x-5)
Expand brackets in the right part
8*x-18 = 6*x-2*x+2*5
Looking for similar summands in the right part:
-18 + 8*x = 10 + 4*x
Move free summands (without x)
from left part to right part, we given:
$$8 x = 4 x + 28$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 28$$
Divide both parts of the equation by 4
x = 28 / (4)
We get the answer: x = 7
