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:
$$10 x = 6 x + 60$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 60$$
Divide both parts of the equation by 4
We get the answer: x = 15
10*(x-8) = 6*x-20
Expand brackets in the left part
10*x-10*8 = 6*x-20
Move free summands (without x)
from left part to right part, we given:
$$10 x = 6 x + 60$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = 60$$
Divide both parts of the equation by 4
x = 60 / (4)
We get the answer: x = 15
