The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 10
We get the answer: x = 12
13*x+x-4*x = 120
Looking for similar summands in the left part:
10*x = 120
Divide both parts of the equation by 10
x = 120 / (10)
We get the answer: x = 12
