Verified answer
X + y = 60x - y = 30
-------------- +
<=>2x = 90
<=> x = 90/2
<=> x = 45
x + y = 60
y = 60 - x
y = 60 - 45
y = 15
Jadi, bilangan itu adalah 45 dan 15
Verified answer
X + y = 60 x + y = 60x - y = 30 x + 15 = 60
--------------- - x = 60 -15
2y = 30 x = 45
y = 30 = 15
---- Jadi, nilai x adalah 45 dan y adalah 15.
