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:
$$9 x = 5 x - 22$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -22$$
Divide both parts of the equation by 4
We get the answer: x = -11/2
2*(7*x+11)-5*x = 5*x
Expand brackets in the left part
2*7*x+2*11-5*x = 5*x
Looking for similar summands in the left part:
22 + 9*x = 5*x
Move free summands (without x)
from left part to right part, we given:
$$9 x = 5 x - 22$$
Move the summands with the unknown x
from the right part to the left part:
$$4 x = -22$$
Divide both parts of the equation by 4
x = -22 / (4)
We get the answer: x = -11/2
