Answer:

x=1 y=2

Step-by-step explanation:

x=1 y=2

8x +4 y=16

8(1) + 4(2)=16

8+8=16

this is correct so now lets check the other one

7y=15-x

7(2)=15-(1)

14=14

this is also correct

-1/3(px-2) = 9

ok! so first we want to isolate x.

multiply both sides by -3/1 (this is the reciprocal of -1/3)

(px-2) = -27

px = -27 + 2

px = -25

x = -25/p

hope this helped!
