The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 7
We get the answer: x = 100/7
x+2*x+4*x = 100
Looking for similar summands in the left part:
7*x = 100
Divide both parts of the equation by 7
x = 100 / (7)
We get the answer: x = 100/7
