The solution
Detail solution
Given the linear equation:
Move free summands (without x)
from left part to right part, we given:
$$4 x = - 5 x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = -12$$
Divide both parts of the equation by 9
We get the answer: x = -4/3
4*x+5 = -5*x-7
Move free summands (without x)
from left part to right part, we given:
$$4 x = - 5 x - 12$$
Move the summands with the unknown x
from the right part to the left part:
$$9 x = -12$$
Divide both parts of the equation by 9
x = -12 / (9)
We get the answer: x = -4/3
