How to solve an inequality algebra

WebTake the solution (s) and put them in the original equation to see if they really work. Example: solve for x: 2x x − 3 + 3 = 6 x − 3 (x≠3) We have said x≠3 to avoid a division by zero. Let's multiply through by (x − 3): 2x + 3 (x−3) = 6 Bring the 6 to the left: 2x + 3 (x−3) − 6 = 0 Expand and solve: 2x + 3x − 9 − 6 = 0 5x − 15 = 0 5 (x − 3) = 0 WebIn order to solve inequalities: Rearrange the inequality so that all the unknowns are on one side of the inequality sign. Rearrange the inequality by dividing by the x x coefficient so that ‘x’ ‘x’ is isolated. Write your solution with the inequality symbol.
