Question

afla nr necunoscut (95-9×5-9×l)÷8=9×4-8×4​

Answer 1

Răspuns:

I=2

Explicație pas cu pas:

(95-9×5-9×l)÷8=9×4-8×4​

(95-45-9×l)÷8=36-32

(50​-9×l)÷8=4

50​-9×l=4×8

50​-9×l=32

9×l=50-32

9×l=18

l=18÷9

I=2

Answer 2

( 95 - 9 × 5 - 9 × l ) : 8 = 9 × 4 - 8 × 4

( 95 - 45 - 9 × l ) : 8 = 36 - 32

( 50 - 9 × l ) : 8 = 4

50 - 9 × l = 4 × 8

50 - 9 × l = 32

9 × l = 50 - 32

9 × l = 18

l = 18 : 9

l = 2
