Question

150:{[(a-3)*2+6]:5+32:4}-3*4=3

Answer 1

Răspuns:  a = 5

Explicație pas cu pas:

150 : { [ ( a - 3 ) × 2 + 6 ] : 5 + 32 : 4 } - 3 × 4 = 3

150 : { [ ( a - 3 ) × 2 + 6 ] : 5 + 8 } - 12 = 3

150 : { [ ( a - 3 ) × 2 + 6 ] : 5 + 8 } = 3 + 12

150 : { [ ( a - 3 ) × 2 + 6 ] : 5 + 8 } = 15

[ ( a - 3 ) × 2 + 6 ] : 5 + 8 = 150 : 15

[ ( a - 3 ) × 2 + 6 ] : 5 + 8 = 10

[ ( a - 3 ) × 2 + 6 ] : 5 = 10 - 8

[ ( a - 3 ) × 2 + 6 ] : 5 = 2

( a - 3 ) × 2 + 6 = 2 × 5

( a - 3 ) × 2 + 6 = 10

( a - 3 ) × 2 = 10 - 6

( a - 3 ) × 2 = 4

a - 3 = 4 : 2

a - 3 = 2

a = 2 + 3

a = 5 → numărul
