Question

Penyelesaian dari
1/2(x + 3) = 1/4(3x - 1)

Answer 1

1/2(x + 3)= 1/4(3x - 1)
1/2x + 3/2= 3/4x - 1/4
4(1/2x + 3/2)= 4(3/4x - 1/4)
2x + 6= 3x - 1
2x - 3x= -1 - 6
-x= -7
x= 7

Hp= {7}

Answer 2

1/2x + 3/2 = 3/4x - 1/4
1/2x - 3/4x = -1/4 - 3/2
(yang bawahnya di bagi 12)
6x - 9x = -3 -18
-3x = -21
x = -21 : -3
x = 21 : 3
x = 7
