An you help me now with these |x + 2| + 16 = 1 i need help :( |2x + 6| − 4 = 20 nd help solving
krok68 [10]
|x + 2| + 16 = 1
<u>           - 16  - 16</u>
        |x + 2| = -15
         x + 2 = -15    U    x + 2 = 15
         <u>    - 2     - 2</u>          <u>    - 2    - 2</u>
               x = -17                 x = 13

|2x + 6| - 4 = 20
<u>            + 4   + 4</u>
     |2x + 6| = 24
      2x + 6 = 24    U    2x + 6 = -24
      <u>     - 6    - 6</u>           <u>     - 6      - 6</u>
            <u>2x</u> = <u>18</u>                 <u>2x</u> = <u>-30</u>
             2      2                   2       2
              x = 9                     x = -15
