What ordered pairs are a solution to the equations

3x-5y=4
-5x+4y=2

(-7,0)
(6,8)
(3,1)
(-2,-2)

x=-2, y=-2. (-2, -2)

Step-by-step explanation:

3x-5y=4

-5x+4y=2

5(3x-5y)=5(4)

3(-5x+4y)=3(2)

15x-25y=20

-15x+12y=6

-13y=26

y=26/-13

y=-2

3x-5(-2)=4

3x+10=4

3x=4-10

3x=-6

x=-6/3

x=-2

x=-2, y=-2.

g = (2, 2)

step-by-step explanation:

given the ratio is 1 : 1 then f is the midpoint of eg

let the coordinates of g = (x, y)

using the midpoint formula

(0 + x) = 1 ( multiply both sides by 2 )

0 + x = 2 ⇒ x = 2

similarly

(4 + y) = 3 ( multiply both sides by 2 )

4 + y = 6 ( subtract 4 from both sides )

y = 2

coordinates of g = (2, 2)

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
