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 -6
We get the answer: x = -4
1-2*(5+3*x) = 15
Expand brackets in the left part
1-2*5-2*3*x = 15
Looking for similar summands in the left part:
-9 - 6*x = 15
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -6
x = 24 / (-6)
We get the answer: x = -4
