Question

помогите пж !! решите уравнение : |6x-4|=15;. |9x-5|+3=9​

Answer 1

$|6x - 4| = 15 \\ 6x - 4 = 15 \: or \: 6x - 4 = - 15 \\ x = 3 \frac{1}{6} \: or \: x = - 1 \frac{5}{6}$

$|9x - 5| + 3 = 9 \\ |9x - 5| = 6 \\ 9x - 5 = 6 \: or \: 9x - 5 = - 6 \\ x = 1 \frac{2}{9} \: or \: x = - \frac{1}{9}$
