1. 3 ( x - 2 ) = 5 x - 162. -6 ( 2 x + 1 ) = 3 ( x + 5 )

1. 3 ( x – 2 ) = 5 x – 162. -6 ( 2 x + 1 ) = 3 ( x + 5 )

$rm3(x - 2) = 5x - 16$

$rm3x - 6 = 5x - 16$

$rm 3x - 5x = - 16 + 6$

$rm - 2x = - 10$

$rm x = dfrac{ - 10 }{ - 2}$

$rm x = red{ bold{5}}$

$:$

$rm - 6(2x + 1) = 3(x + 5)$

$rm - 12x - 6 = 3x + 15$

$rm - 12x - 3x = 15 + 6$

$rm - 15x = 21$

$rm x = dfrac{21}{ - 15}$

$rm x = dfrac{7}{ - 5}$

$rm x = red{ bold{ - dfrac{7}{5} }} : atau : red{ bold{ - 1 dfrac{2}{5} }} : atau : red{ bold{ - 1,4}}$
