Solving Two-Step Equations
The algorithm for solving two-step equations may also be used to solve two-step inequalities.
2x       +    8            = 28
(co-efficient)   (variable)    (constant)
2x+8=28
Step 1 - Add the opposite of the constant to both sides of the equation.
2x +  8 =  28
     +(-8) +(-8)
2x = 20
Step 2 - Divide both sides of the equation by the co-efficient.
2x = 20
