Bilangan 1 = x
Bilangan 2 = y
Maka,
x +y = 20 -----------> x = 20 -y
x -y = 8
x -y = 8
(20 -y) -y = 8
20 -2y = 8
-2y = 8 -20
-2y = -12
y = -12/-2
y = 6
x = 20 -y
x = 20 -6
x = 14
Maka nilai :
x . y
= 14 . 6
= 84
Itu jawabannya.
bilangan 2 = y
x + y = 20
x - y = 8 -
2y = 12
y = 6
cari x, subtitusikan y
x + y = 20
x + 6 = 20
x = 20-6
x = 14
hasil kali x × y = 14 × 6 = 84
