Solving One-Step Inequalities

Solving One-Step Inequalities 1.6 - Solution

arrow_back Return to Solving One-Step Inequalities
We are given the inequality and Mika's steps . In the first step, the goal is to move to the right-hand side, and the inverse operation of subtracting is adding We can see that Mika added on the left-hand side but subtracted from the right-hand side. This is not correct since the operation must be the same on both sides to make sure that the equality still holds. Therefore, let's correct this error.
The correct solution set is and not We can graph this by using an open circle at This indicates that is not part of the solution. Then we shade the values to the right of to indicate that all numbers greater than are solutions.
