If some one could figure out the x and y are
The problem is
3x+4y=50
-2x=y

x = -10

y = 20

Step-by-step explanation:

y = -2x

so

substituting the value in equation ii

3x + 4y = 50

or, 3x + 4(-2x) = 50

or, 3x + (-8x) = 50

or, 3x-8x = 50

or, -5x = 50

so, x = -10

so

y = -2x

or, y = -2*(-10)

so, y = 20

55/i dont know i do it for the points

step-by-step explanation:

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
