The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$4 x = 6 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 6$$
Divide both parts of the equation by 5
We get the answer: x = 6/5
1-2*(5-2*x) = -x-3
Expand brackets in the left part
1-2*5+2*2*x = -x-3
Looking for similar summands in the left part:
-9 + 4*x = -x-3
Move free summands (without x)
from left part to right part, we given:
$$4 x = 6 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$5 x = 6$$
Divide both parts of the equation by 5
x = 6 / (5)
We get the answer: x = 6/5
