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:
$$- 19 x = 19$$
Divide both parts of the equation by -19
We get the answer: x = -1
x+5*(2-4*x) = 29
Expand brackets in the left part
x+5*2-5*4*x = 29
Looking for similar summands in the left part:
10 - 19*x = 29
Move free summands (without x)
from left part to right part, we given:
$$- 19 x = 19$$
Divide both parts of the equation by -19
x = 19 / (-19)
We get the answer: x = -1
