The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = 127$$
Divide both parts of the equation by 3
We get the answer: x = 127/3
3*x-50 = 77
Move free summands (without x)
from left part to right part, we given:
$$3 x = 127$$
Divide both parts of the equation by 3
x = 127 / (3)
We get the answer: x = 127/3
