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:
$$- 10 x = 30$$
Divide both parts of the equation by -10
We get the answer: x = -3
2-5*(3+2*x) = 17
Expand brackets in the left part
2-5*3-5*2*x = 17
Looking for similar summands in the left part:
-13 - 10*x = 17
Move free summands (without x)
from left part to right part, we given:
$$- 10 x = 30$$
Divide both parts of the equation by -10
x = 30 / (-10)
We get the answer: x = -3
