The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$3 x = -15$$
Divide both parts of the equation by 3
We get the answer: x = -5
3*x-4 = -19
Move free summands (without x)
from left part to right part, we given:
$$3 x = -15$$
Divide both parts of the equation by 3
x = -15 / (3)
We get the answer: x = -5
