The solution
Detail solution
Given the linear equation:
Expand brackets in the right part
Looking for similar summands in the right part:
Move free summands (without x)
from left part to right part, we given:
$$2 x = - 4 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -18$$
Divide both parts of the equation by 6
We get the answer: x = -3
2*x+3 = x-5*(x+3)
Expand brackets in the right part
2*x+3 = x-5*x-5*3
Looking for similar summands in the right part:
3 + 2*x = -15 - 4*x
Move free summands (without x)
from left part to right part, we given:
$$2 x = - 4 x - 18$$
Move the summands with the unknown x
from the right part to the left part:
$$6 x = -18$$
Divide both parts of the equation by 6
x = -18 / (6)
We get the answer: x = -3
