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 = 102
6*x+8*x-7*x = 714
Looking for similar summands in the left part:
7*x = 714
Divide both parts of the equation by 7
x = 714 / (7)
We get the answer: x = 102
