The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = - 6 x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -9$$
Divide both parts of the equation by 10
We get the answer: x = -9/10
4*x+4 = -6*x-5
Move free summands (without x)
from left part to right part, we given:
$$4 x = - 6 x - 9$$
Move the summands with the unknown x
from the right part to the left part:
$$10 x = -9$$
Divide both parts of the equation by 10
x = -9 / (10)
We get the answer: x = -9/10
