ten taki ptaszek nazywa się klamra ;) a) (u=4v (5u-v=10 u = 4v 5 * 4v - v = 10 u=4v 20v -v =10 u=4v 19v = 10 /:19 u=4v v = 1,9 u = 4 * 1,9 v= 1,9 u = 7,6 v= 1,9 b) (3r=s (3r+s=24 3r = s s + s = 24 3r = s 2s = 24 /:2 3r=s s = 12 3r = 12 /:3 r=4
a) (u=4v (5u-v=10 u = 4v - podstawiamy 4v za u w dziłaniu drugim (u=4v (5*(4v)-v=10 Oblczamy v: 20v - v =10 19v = 10 /:19 v = 10/19 Podstawiamy z powrotem do pierwszego działania: u=4v u = 4*(10/19) u = 40/19 u = 2 2/19 Drugie działanie robimy podobnie: b) (3r=s (3r+s=24 (3r=s (s+s=24 2s = 24 /:2 s = 12 3r = s 3r = 12 r = 12/3 = 4
b) 3r=s 3r=s=24 3r=s s+s=24 3r=s 2s=24/:2 3r=s s=12 3r=12/:3 s=12 r=4 s=12
