Question

Find the value of=P
And find the value of=Y
P-Y=18
P+Y=12​

Answer 1

Step-by-step explanation:

P-Y=18. 1

P+Y=12. 2

SUBTACT 2 FROM 1

P+Y-(P-Y)=12-18

P+Y-P+Y=-6

2Y=-6

Y=-3

P+Y=12

P-6=12

P=18

SO P=18. Y=-3

Answer 2

Answer:

Let us take P-Y=18

then, P=18+Y

Put this in P+Y=12

18+Y+Y=12

18+2Y=12

2Y=12-18

2Y=-6

Y=-6/2

Y=-3

PUT IN P+Y=12 (or in any equation. its optional )

P-3=12

P=12+3

P=15

ITS YOUR ANSWER.
