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:
$$9 x = 45 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 45$$
Divide both parts of the equation by 10
We get the answer: x = 9/2
9*(x-5) = -x
Expand brackets in the left part
9*x-9*5 = -x
Move free summands (without x)
from left part to right part, we given:
$$9 x = 45 - x$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = 45$$
Divide both parts of the equation by 10
x = 45 / (10)
We get the answer: x = 9/2
