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:
$$x = - 6 x - 35$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -35$$
Divide both parts of the equation by 7
We get the answer: x = -5
20+x = 3*(3-2*x)-24
Expand brackets in the right part
20+x = 3*3-3*2*x-24
Looking for similar summands in the right part:
20 + x = -15 - 6*x
Move free summands (without x)
from left part to right part, we given:
$$x = - 6 x - 35$$
Move the summands with the unknown x
from the right part to the left part:
$$7 x = -35$$
Divide both parts of the equation by 7
x = -35 / (7)
We get the answer: x = -5
