The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 10/9
We get the answer: x = -3
x+x/9 = -10/3
Looking for similar summands in the left part:
10*x/9 = -10/3
Divide both parts of the equation by 10/9
x = -10/3 / (10/9)
We get the answer: x = -3
