Question

y-15) x 2- [18 - 18:3+ (100 – 5 x 15) x 0 ] = 12

Answer 1

Răspuns:

(y-15)*2-[18-18:3+(100-5*15)*0]=12

2y-30-(18-6+0)=12

2y-30-12=12

2y=12+30+12

2y=54

y=54:2

y=27

Answer 2

Răspuns:

y = 27

Explicație pas cu pas:

( y - 15 ) x 2 - [ 18 - 18 : 3 + ( 100 - 5 x 15 ) x 0 ] = 12

( y - 15 ) x 2 - [ 18 - 18 : 3 + ( 100 - 75 ) x 0 ] = 12

( y - 15 ) x 2 -[ 18 - 18 : 3 + 25 x 0 ] = 12

( y - 15 ) x 2 - ( 18 - 6 + 0 ) = 12

( y - 15 ) x 2 - ( 12 + 0 ) = 12

( y - 15 ) x 2 -12 = 12

( y - 15 ) x 2 = 12 + 12

( y - 15 ) x 2 = 24

y - 15 = 24 : 2

y - 15 = 12

y = 12 + 15

y = 27
