Question

14. Află numărul necunoscut:
a - 2043 = 1660 1504 + a = 3000
5003 - a = 4061
a: 3 = 24
b: 2 = 301
10 x a = 700
(a + 60 ): 3 = 45
(808 - a): 2 =141
Va rog rapid

Answer 1

a-2043=1660=>a=1660+2043=3073

5003-a=4061=>a=5003-4061=942

a:3=24=>a=24×3=72

b:2=301=>b=301×2=602

10×a=700=>a=700:10=70

(a+60):3=45=>a+60=45×3=>a+60=135=>a=135-60=75

(808-a):2=141=>808-a=141×2=>808-a=282=>a=808-282=566
