Learn how to do two step math problems with this video tutorial.
It is used to know the value of variable present in an equation which consists of one unknown variable. Consider an equation 5A+2=27. In the first step take 2 from LHS side to RHS that means, 27-2=25. Now in the LHS side we have 5A and in RHS we have 25. Now divide the 25 by 5( 5A=25 implies A=25/5). Then we get the result A=5. This is a single step to know the unknown variable.
