$frac{1}{3} (x - 2) = frac{1}{3} x - frac{2}{3}$
$frac{1}{3} x - frac{2}{3} = frac{2}{3} x - frac{13}{3}$
kumpulkan x di ruas kiri, konstanta (angka) di ruas kanan
$frac{1}{3} x - frac{2}{3} x = - frac{13}{3} + frac{2}{3}$
$- frac{1}{3} x = - frac{11}{3}$
kalikan ke 2 ruas dengan angka 3
$3( - frac{1}{3x} ) = 3( - frac{11}{3} )$
$- x = - 11$
maka
$x = 11$

D)
$frac{1}{3}( x - 2) = frac{2}{3} x - frac{13}{3} : : (semua : suku: dikali : 3) \ 3 times frac{1}{3}( x - 2) = 3 times frac{2}{3} x - 3 times frac{13}{3} \ x - 2 = 2x - 13 \ x - 2x = - 13 + 2 \ - x = - 11 \ x = 11$

e)
$2( frac{1}{2} x + frac{3}{2} ) - frac{7}{2} = frac{3}{2} (x + 1) - ( frac{1}{2} x + 2) : : (semua : suku : dikali : 2) \ 2 times 2( frac{1}{2} x + frac{3}{2} ) - 2 times frac{7}{2} = 2 times frac{3}{2} (x + 1) -2 times ( frac{1}{2} x + 2) \ 2x + 6 - 7 = 3x + 3 - x - 4 \ 2x - 1 = 3x - x + 3 - 4\ 2x - 1 = 2x - 1 \ 2x - 2x = - 1 + 1 \ 0 = 0$
