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:
Divide both parts of the equation by 2
We get the answer: x = -17
(x+24)+(x+10) = 0
Expand brackets in the left part
x+24+x+10 = 0
Looking for similar summands in the left part:
34 + 2*x = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by 2
x = -34 / (2)
We get the answer: x = -17
