The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 5/12
We get the answer: x = 9
x/3+x/12 = 15/4
Looking for similar summands in the left part:
5*x/12 = 15/4
Divide both parts of the equation by 5/12
x = 15/4 / (5/12)
We get the answer: x = 9
