The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 4
We get the answer: x = -7/4
4*x+7 = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 4
x = -7 / (4)
We get the answer: x = -7/4
