What is the solution to this system?
equation a: -x+y=0
equation b: x=-y-10

The answer is x = -5, y = -5

Step-by-step explanation:

Use the method of elimination

Rearrange the equations

x = -y - 10 → x + y = -10

-x + y = 0

x + y = -10

Add these two equations together to eliminate the xs

2y = -10

y = -5

-x + y = 0

-x -5 = 0

-x = 5

x = -5

(-5,-5) Is the solution

the number of possible outcomes that do not show a 1 on the first spinner and show the number 4 on the second spinner is 2.

1                     4

2                   1

2                   2

2                   3

2                   4   = not 1, and 4

3                   1

3                   2

3                   3

3                   4 = not 1, and 4

only 2 outcomes have passed the given condition.
