The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 15/8
We get the answer: x = 22/5
7/8*x+x = 33/4
Looking for similar summands in the left part:
15*x/8 = 33/4
Divide both parts of the equation by 15/8
x = 33/4 / (15/8)
We get the answer: x = 22/5
