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:
$$7 x = 1771$$
Divide both parts of the equation by 7
We get the answer: x = 253
(x-245)*7 = 56
Expand brackets in the left part
x*7-245*7 = 56
Move free summands (without x)
from left part to right part, we given:
$$7 x = 1771$$
Divide both parts of the equation by 7
x = 1771 / (7)
We get the answer: x = 253
