The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Looking for similar summands in the right part:
Divide both parts of the equation by 9
We get the answer: x = 18
56*x-47*x = 8961/29/3+59
Looking for similar summands in the left part:
9*x = 8961/29/3+59
Looking for similar summands in the right part:
9*x = 162
Divide both parts of the equation by 9
x = 162 / (9)
We get the answer: x = 18
