y = -3
Step-by-step explanation:
-8x - 5y = -1
+8x +8x
-5y = 8x - 1
÷-5 ÷-5 ÷-5
y =![-\frac{8}{5}x + \frac{1}{5}](/tpl/images/0048/9953/886a6.png)
y(2) =![-\frac{8}{5}(2) + \frac{1}{5}](/tpl/images/0048/9953/05e52.png)
=![-\frac{16}{5} + \frac{1}{5}](/tpl/images/0048/9953/9a3c1.png)
=![-\frac{15}{5}](/tpl/images/0048/9953/2376b.png)
