The solution
Detail solution
Given the linear equation:
Looking for similar summands in the left part:
Divide both parts of the equation by 7/12
We get the answer: x = -36
x/3+x/4 = -21
Looking for similar summands in the left part:
7*x/12 = -21
Divide both parts of the equation by 7/12
x = -21 / (7/12)
We get the answer: x = -36
