The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 5/4
We get the answer: x = 16/5
x/4+x = 4
Looking for similar summands in the left part:
5*x/4 = 4
Divide both parts of the equation by 5/4
x = 4 / (5/4)
We get the answer: x = 16/5
