The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Move free summands (without k)
from left part to right part, we given:
$$\frac{k}{23} = \frac{610}{23}$$
Divide both parts of the equation by 1/23
We get the answer: k = 610
(k+11)/23 = 27
Expand brackets in the left part
k/23+11/23 = 27
Move free summands (without k)
from left part to right part, we given:
$$\frac{k}{23} = \frac{610}{23}$$
Divide both parts of the equation by 1/23
k = 610/23 / (1/23)
We get the answer: k = 610
