The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by -81
We get the answer: x = -5/81
154*x-235*x = 5
Looking for similar summands in the left part:
-81*x = 5
Divide both parts of the equation by -81
x = 5 / (-81)
We get the answer: x = -5/81
