The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by -5
We get the answer: a = 0
2*a-7*a = 0
Looking for similar summands in the left part:
-5*a = 0
Divide both parts of the equation by -5
a = 0 / (-5)
We get the answer: a = 0
