The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 8
We get the answer: x = 84
17*x-9*x = 672
Looking for similar summands in the left part:
8*x = 672
Divide both parts of the equation by 8
x = 672 / (8)
We get the answer: x = 84
