Question

2p - 3q + 4r - 8s,when p=20, q=8, r=6 and s=2

Answer 1

(2×20=40)-(3×8=24)+(4×6=24)-(8×2=16)
40-24+24-16
40+24-24-16
64-40
24

Answer 2

Answer:

20 + 24  = 44 - 24 = 20 - 16 = 4

Explanation:

2p - 3q + 4r -8s, when p = 10, q = 8, r = 6 and s = 2

= (2×10) - (3×8) + (4×6) - (8×2 )

= 20 - 24 + 24 - 16

= 20 + 24 - 24 - 16

= 4
