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:
$$4 x = 312$$
Divide both parts of the equation by 4
We get the answer: x = 78
4*(x-15) = 252
Expand brackets in the left part
4*x-4*15 = 252
Move free summands (without x)
from left part to right part, we given:
$$4 x = 312$$
Divide both parts of the equation by 4
x = 312 / (4)
We get the answer: x = 78
