Berapa nilai x untuk persamaan nilai mutlak (x+2)=(5x-2)

$|x + 2| = |5x - 2|$

$|x + 2| ^{2} = |5x - 2| ^{2}$

${x}^{2} + 4x + 4 = 25 {x}^{2} - 20x + 4$

${x}^{2} - 25 {x}^{2} + 4x + 20x + 4 - 4 = 0$

$- 24 {x}^{2} + 24x = 0$

$- 24( {x}^{2} - x) = 0$

${x}^{2} - x = 0$

$x(x - 1) = 0$

$x = 0 : : , : : 1$
