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:
$$2 x = 19$$
Divide both parts of the equation by 2
We get the answer: x = 19/2
2*(x-5) = 9
Expand brackets in the left part
2*x-2*5 = 9
Move free summands (without x)
from left part to right part, we given:
$$2 x = 19$$
Divide both parts of the equation by 2
x = 19 / (2)
We get the answer: x = 19/2
