Mapel : Matematika
Kelas : VIII SMP
Bab : PLSV

Pembahasan :
3 - (2x - 3)/3 = (5 + x)/2
(5 + x)/2 + (2x - 3)/3 = 3
(15 + 3x + 4x - 6)/6 = 3
(7x + 9)/6 = 3
7x + 9 = 18
7x = 9
x = 9/7

Penyelesaian:

[tex]3 - \frac{2x-3}{3} = \frac{5+x}{2} [/tex]
[tex]\frac{9-2x+3}{3} = \frac{5+x}{2} [/tex]
24 - 4x = 15 + 3x
7x = 9
x = 9/7
