The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$8 x = -94$$
Divide both parts of the equation by 8
We get the answer: x = -47/4
8^2+8*x+30 = 0
Move free summands (without x)
from left part to right part, we given:
$$8 x = -94$$
Divide both parts of the equation by 8
x = -94 / (8)
We get the answer: x = -47/4
