Question

Afla numarul necunoscut:
8 x 4 + a = 6 x 9 + 16 : 2
a – 9 x 8 = 32 : 4 + 225
( 6 x 6 : 4 x b) – 25 : 5 = 11 x 2

Answer 1

Răspuns:

8×4+a=6×9+16:2

32+a=54+8

32+a=62

a=62-32

a=30

a-9×8=32:4+225

a-72=8+225

a-72= 233

a=233+72

a=305

(6×6:4×b)-25:5=11×2

(36:4×b)-5=22

(9×b)-5=22

9×b=22+5

9×b=27

b=27:9

b=3
