3x+5=5x-3
3x-5x=-3-5
-2x=-8
x=8/2
x=4
maka x+1=4+1=5
2 4 2

Jika 3X + 5 = 5X - 3, maka nilai X + 1 ?

3X + 5  = 5X - 3
3X - 5X  = -5 -3
-2X       = -8
 X         = -8:-2
         X = 4
Maka, X + 1 = 4 + 1 = 5

Bener ngga sih ?

3X + 5 = 0
3x + 5 = 0
5x - 3 = 0
-2x + 8 = 0
8 = 2x
x = 4

jadi, x + 1 = 4 + 1 = 5
