The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 8
We get the answer: x = 7/2
-x = 4-3*(3*x-8)
Expand brackets in the right part
-x = 4-3*3*x+3*8
Looking for similar summands in the right part:
-x = 28 - 9*x
Move the summands with the unknown x
from the right part to the left part:
Divide both parts of the equation by 8
x = 28 / (8)
We get the answer: x = 7/2
