Diketahui 2x + 5 = 6x – 3. Nilai x – 3 adalah?

2x + 5 = 6x – 3
5 + 3 = 6x – 2x
8 = 4x
x = 2

x – 3= 2 – 3 = – 1

2x + 5 = 6x – 3
2x – 6x = -3 + (-5)
-4x = -8
x = -8/-4
x = 2
jadi, nilai x adalah 2.
Ditanya : nilai x – 3.
jawab : Nilai x – 3 = 2 – 3
                             -1 . Jadi, nilai x – 3 = -1 😉
