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:
$$- 5 x = - 8 x - 21$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -21$$
Divide both parts of the equation by 3
We get the answer: x = -7
11-5*x = 2*(3-4*x)-16
Expand brackets in the right part
11-5*x = 2*3-2*4*x-16
Looking for similar summands in the right part:
11 - 5*x = -10 - 8*x
Move free summands (without x)
from left part to right part, we given:
$$- 5 x = - 8 x - 21$$
Move the summands with the unknown x
from the right part to the left part:
$$3 x = -21$$
Divide both parts of the equation by 3
x = -21 / (3)
We get the answer: x = -7
