15 points + Brainlest Determine if the following system of equations has no solutions, infinitely many solutions or exactly one solution.
x+y=-4
-2x-2y=6

Step-by-step explanation:

x+y=-4  One solution of -4

-2x-2y=6 One solution of -3

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)
