I did the work lol

Answer 2

Answer:

y = 9/2 or 4.5

Step-by-step explanation: hope this helps :)

x-y= -5   So what you do here is isolate the variables

+y     +y      

x = -5+y

After you do this you input the equation as x

2x+y = -1

2(-5+y) = -1

-10 + 2y = -1

+ 10         +10

2y = -9

/2      /2

y =  9/2 or 4.5
