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 -20
We get the answer: x = 1
-14*x+(20-6*x) = 0
Expand brackets in the left part
-14*x+20-6*x = 0
Looking for similar summands in the left part:
20 - 20*x = 0
Move free summands (without x)
from left part to right part, we given:
Divide both parts of the equation by -20
x = -20 / (-20)
We get the answer: x = 1
