Question

|||2х+7|-3|+6|=6 решить уравнение

Answer 1

$| | |2x + 7| - 3 | + 6 | = 6 \\ | |2x + 7| - 3 | + 6 = 6 \\ | |2x + 7| - 3 | = 0 \\ |2x + 7| - 3= 0 \\ |2x + 7| = 3 \\ \\ 2x + 7 = 3 \\ 2x = 3 - 7 \\ 2x = - 4 \\ x = - 4 \div 2 \\ \bold{x_1= - 2} \\ \\ 2x + 7 = - 3 \\ 2x = - 3 - 7 \\ 2x = - 10 \\ x = - 10 \div 5 \\ \bold{x_2 = - 5}$
