Solving Inequalities by Adding or Subtracting The method for solving one-step Inequalities by adding is just like the method for solving one-step equations by adding. Solve x - 2 = 1 and graph the solution. x - 2=1 Solve x - 2 2: 1 and graph the solutions. +2+2 x- 221 Add 2 to each side. x =3 +2 +2 Add 2 to each side. X23 Solve -4 = a - 3 and graph the solution. Solve -4> a - 3 and graph the solutions. -4- a- 3 -4> a - 3 +3 +3 Add 3 to each side. +3 + 3 Add 3 to each side. -1 = a -1> a a-6+ x 4. 1 sf - 3 -8-7-6-5-4-3-2- 2 8 7 -8-7-6-5-4-3-2-1
