The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 3
We get the answer: x = 44
7*x+x-5*x = 132
Looking for similar summands in the left part:
3*x = 132
Divide both parts of the equation by 3
x = 132 / (3)
We get the answer: x = 44
