1/3x + 2/5y + 2/5=1 find x,y?​

Ubah jadi bentuk standar

1/3x + 2/5y + 2/5 = 1

= 1/3x + 2/5y = 1 – 2/5

= 1/3x + 2/5y = 3/5

= 15 (1/3x + 2/5y) = 15 (3/5)

= 5x + 3y X 2y = 3 X 3

= 5x + 6y = 9

Cari nilai x dengan misalkan y = 0

5x + 6 X 0 = 9

5x = 9

x = 9/5

Cari nilai y dengan misalkan x = 0

5 X 0 + 6y = 9

6y = 9

y = 3/2

Jadi x = 9/5 dan y = 3/2
