If y=-3x + 2, find x when y= -13 *
Arturiano [62]

Answer:

x = 5

Step-by-step explanation:

You know what "y" equals, so you just need to insert the value into the equation, then solve for "x".

-13 = -3x + 2

-13 - 2 = -3x

-(-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)
