Question

решите уравнениет 1) |3х+4|=2 2) |2х+1|+13=14

Answer 1

$1)|3x + 4| = 2 \ 3x + 4 = 2 \ 3x = 2 - 4 \ 3x = - 2 \ \ x = - frac{2}{3} \ \ 3x + 4 = - 2 \ x = - 2 \ \ x1 = - 2 \ x2 = - frac{2}{3} \ \ 2) |2x + 1| + 13 = 14 \ |2x + 1 | = 14 - 13 \ |2x + 1| = 1 \ 2x + 1 = 1 \ 2x = 0 \ x = 0 \ 2x + 1 = - 1 \ x = - 1 \ x1 = - 1 \ x2 = 0$
