Question

Complete the solution of the equation. Find the value of y when x equals -15. -x ‒ 8y = -1

Answer 1

To complete the solution of - x - 8y = -1, we first need to substitute x for -15.
As so:

-(-15) - 8y = -1
15 - 8y = -1

Next, we can subtract 15 from each side to get:

15 - 15 - 8y = -1 - 15
- 8y = -16

Now, we can divide by -8 on each side to get the y by itself:

-8y / -8 = -16 / -8 
y = -16 / -8
y = 2

There we go! y = 2 when x = -15! Hope I could help you out! Have a good one.
