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:
$$5 x = 215$$
Divide both parts of the equation by 5
We get the answer: x = 43
(x+30)*5 = 365
Expand brackets in the left part
x*5+30*5 = 365
Move free summands (without x)
from left part to right part, we given:
$$5 x = 215$$
Divide both parts of the equation by 5
x = 215 / (5)
We get the answer: x = 43
