Penjelasan dengan langkah-langkah:

$1.6x + 3 = 9$

$6x = 9 - 3$

$6x = 6$

$x = 1$

$2.3x + 4 = 19$

$3x = 19 - 4$

$3x = 15$

$x = frac{15}{3}$

$x = 5$

$3.5x - 11 = 2(x + 2)$

$5x - 2x = 4 + 11$

$3x = 15$

$x = frac{15}{3}$

$x = 5$

$4.6 = frac{2x - 4}{7}$

$7 times 6 = 7 times frac{2x - 4}{7}$

$42 = 2x - 4$

$- 2x = - 4 - 42$

$- 2x = - 46$

$x = frac{ - 46}{ - 2}$

$x = 23$

$5. frac{x - 4}{6} = frac{2x + 3}{2}$

$2(x - 4) = 6(2x + 3)$

$2x - 8 = 12x + 18$

$2x - 12x = 18 + 8$

$- 10x = 26$

$x = frac{ 26}{ - 10}$

$x = - frac{13}{5}$
