Y + ( -a + x - y ) + b =


jika diketahui Y = 60​

Answer 1

Verified answer

Penjelasan dengan langkah-langkah:

AljabAr

x + a - b = 30

x - b = 20

a + b = 15

Y -a + x - y + b = ?

x + a - b = 30

x - b = 30 - a

x - b = 20

30 - a = 20

a = 30 - 20

a = 10

a + b = 15

10 + b = 15

b = 15-10

b = 5

x - b = 20

x - 5 = 20

x = 20 + 5

x = 25

Y - a + x - y + b

= 60 - 10 + 25 - 60 + 5

= -10 + 25 + 5

= -10 + 30

= 20

Hasil operasi Aljabar diatas adalah 20
