Question

∣x−3∣+∣3−x∣=16

помогите пожалуйста ​

Answer 1

$\bf |x - 3| + |3 - x| = 16 \\ \\ \bf |x - 3| + | - (x - 3)| = 16 \\ \\ \bf |x - 3| + |x - 3| = 16 \\ \\ \bf 2 \times |x - 3| = 16 \\ \\ \bf |x - 3| = \frac{16}{2} \\ \\ \bf |x - 3 | = 8 \\ \\ \bf x - 3 = 8 \\ \bf x - 3 = - 8 \\ \\ \red{ \boxed{ \bf x_1 = - 5 \: \: \: \: \: \: \: \: \: \: x_2 = 11} }$
