9p + 12
-9p + 6p = -3p
9(9p + 5r)(9p + 5r)
15 = 5 +( 9p - 4p) 15 = 5 + 5p 15 - 5= 5 -5 +5p 10 = 5p there for p = 10/5 = 2
9p + 27 = 9(p + 3)
Evaluate 9p + 33 for p = 5
7p+5t
-14 + 3p = -9p - 21 add 14 and 9p to both sides, then 12p = -7 p = -7/12
9p
Equilibrium occurs where Qd = QsQd - 128 + 9p = 0Qd = 128 - 9pQs + 32 - 7p = 0Qs = 7p - 327p - 32 = 128 - 9p16p = 160p = 10
4p - 12 = 3p - 8 - 9p 4p - 3p + 9p = -8 + 12 10p = 4 p = 0.4 (or 2/5)
