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:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 18
We get the answer: x = 5/9
22 = 4*(8-2*x)-10*x
Expand brackets in the right part
22 = 4*8-4*2*x-10*x
Looking for similar summands in the right part:
22 = 32 - 18*x
Move free summands (without x)
from left part to right part, we given:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 18
x = 10 / (18)
We get the answer: x = 5/9
