The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 12
We get the answer: x = 12
19*x-7*x = 144
Looking for similar summands in the left part:
12*x = 144
Divide both parts of the equation by 12
x = 144 / (12)
We get the answer: x = 12
