The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 40
We get the answer: x = 7/5
22*x+18*x = 56
Looking for similar summands in the left part:
40*x = 56
Divide both parts of the equation by 40
x = 56 / (40)
We get the answer: x = 7/5
