Solve each system by adding or subtracting -2x-y=-5,3x+y=-1

Mathematics

Answer:

(-6,17)

Step-by-step explanation:

-2x-y=-5,

 3x+y=-1

Add the two equations together to eliminate t

-2x-y=-5

 3x+y=-1

-------------------

x      = -6

Now that we know x, we can substitute it into one equation to find y

3x+y = 1

3(-6) +y = 1

-18 +y = -1

Add 18 to each side

-18+18 +y = -1+18

y = 17

(-6,17)

Step-by-step explanation:

If we were using feet the expression would be 198x, where x is feet per second

Since they are asking in meters we need to convert feet to meters

When you do that you get 60

Now the expression is 60x

When you plug 5 into the equation it is 300
