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:
$$4 x = 4 x - 44$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -44$$
This equation has no roots
4*x+9 = 5*(2*x-7)-6*x
Expand brackets in the right part
4*x+9 = 5*2*x-5*7-6*x
Looking for similar summands in the right part:
9 + 4*x = -35 + 4*x
Move free summands (without x)
from left part to right part, we given:
$$4 x = 4 x - 44$$
Move the summands with the unknown x
from the right part to the left part:
$$0 = -44$$
This equation has no roots
