SOLUTION: 3p+2y=209 p+y=81 This would be correct right? 3p+2y=209 p=-y+81 Then, 3(-y+81)+2y=209 -3y+243+2y=209 Then, -y=-34 y=34 So, don't you enter y into the equation? Like this

Question 587320: 3p+2y=209
p+y=81
This would be correct right?
3p+2y=209
p=-y+81
Then,
3(-y+81)+2y=209
-3y+243+2y=209
Then,
-y=-34
y=34
So, don't you enter y into the equation? Like this,
p=-y+81
p=-34+81
p=47
So.
y=34 and p=47
My teacher says that this is wrong?
