Solving equations that involve two steps is really two basic equations in one problem. Always do the addition or subtraction part first before solving for the variable using division or multiplication.

Key concepts to keep in mind:

* understand positive and negative number operations first before doing equations

* understand fractions before doing equations

* understand one step basic equations before doing two step equations

some key topics that involve two step equation skills:

* multi-step equations

* systems

* quadratic equations

* rational and radical equations

* graphing and finding the equations of lines

* formulas
