The solution
Detail solution
Given the linear equation:
Expand brackets in the left part
Looking for similar summands in the left part:
Move free summands (without x)
from left part to right part, we given:
$$9 x = x - 56$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = -56$$
Divide both parts of the equation by 8
We get the answer: x = -7
2*(6*x+28)-3*x = x
Expand brackets in the left part
2*6*x+2*28-3*x = x
Looking for similar summands in the left part:
56 + 9*x = x
Move free summands (without x)
from left part to right part, we given:
$$9 x = x - 56$$
Move the summands with the unknown x
from the right part to the left part:
$$8 x = -56$$
Divide both parts of the equation by 8
x = -56 / (8)
We get the answer: x = -7
