The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Divide both parts of the equation by -1
We get the answer: x = 23
-4*x+3*x = 2-16-9
Looking for similar summands in the left part:
-x = 2-16-9
Looking for similar summands in the right part:
-x = -23
Divide both parts of the equation by -1
x = -23 / (-1)
We get the answer: x = 23
