set\ them\ equal\ to\ each\ other \\ -8x-23=-5x-14 \\ -3x-23=-14 \\ -3x=9 \\ x= \frac{9}{-3} \\ x=-3 \\  \\ plug\ in\ OG\ equation \\ y=-8x-23 \\ y=-8(-3)-23 \\ y=24-23 \\ y=1 \\  \\ \boxed {(-3,1)}

Y = -8x - 23
<u>y = -5x - 14</u>
2y = -13x - 37
<u>2y</u> = <u>-13x - 37</u>
 2            2
  y = 6 1/2x - 18 1/2
  6 1/2x - 18 1/2 = -5x - 14
  <u>    +5x                 +5x        </u>
 11 1/2x - 18 1/2 = -14
<u>              +18          +18</u>
               11 1/2x = 4
             <u>  11 1/2x</u> = <u>   4    </u><u>
</u>               11 1/2    11 1/2
                         x = 8/23
y = -5(8/23) - 14
y = -1 17/23 - 14
y= -15 17/23
(x, y) = (8/23, -15 17/23)
