-(-10x-8)=-(4x+10)<br> A)-4<br> B)-2<br> C)-3<br> D)3<br> show work
Eva8 [605]

Answer:

<h3>             None of given </h3><h3>                  x = -1²/₇ </h3>

Step-by-step explanation:

-(-10x - 8) = -(4x + 10)

  10x + 8 = -4x - 10

      -8            -8

     10x  =  -4x - 18

      +4x     +4x

     14x = -18

      ÷14    ÷14

      x = -¹⁸/₁₄ = -⁹/₇ = -1²/₇

I think you meant -(10x-8)=-(4x+10)

Then:

-(10x - 8) = -(4x + 10)

  -10x + 8 = -4x - 10

      -8            -8

     -10x  =  -4x - 18

       +4x     +4x

     -6x  =  -18

      ÷(-6)    ÷(-6)

<h3>         x = 3     D)</h3>
