Question

Tolongin nih gw di remed

Answer 1

Misal tablet 1 = x
         tablet 2 = y
Vitamin A --> 4x + 3y = 24 (x2)
Vitamin B --> 3x + 2y = 7  (x3)

8x + 6y = 48
9x + 6y = 21 -
-x = 27
x = -27

3x + 6y = 7
3(-27) + 6y = 7
-81 + 6y = 7
6y = 7 + 81
6y = 86
y = 43/3

mungkin ada kesalahan dalam soal karena hasil x tidak boleh minus
