    When you have an absolute value equation in which you have the absolute value of an expression is less than a number, you change it like this: |expression| < number negative of the number < expression < number In your case this wuill be: -5 < 2x - 1 < 5

    -5 < 2x - 1 < 5 Add 1 to all three parts: -5 + 1 < 2x < 5 + 1 -4 < 2x < 6 Divide all three parts by 2 -2 < x < 3
