Question

What coordinate pair satisfies both 5x - 3y=22 and -4x + y=-19​

Answer 1

Answer:

hello : coordinate pair is:  (5 ; 1)

Step-by-step explanation:

you have this system :

5x - 3y=22 ......(1)

-4x + y= -19​.....(2)

by (2) : y = 4x -19

put y in (1) : 5x - 3 (4x -19) =22

5x -12x +57 = 22

- 7x = -35

x = 5

but : y = 4x -19  so : y = 4(5) -19   = 1

coordinate pair is:  (5 ; 1)
