Question

Помогите пожалуйста решить!!!!!!!!!

Answer 1

$|y - 4 frac{1}{2} | + 3 |x + frac{1}{2} | = \ = |3 - frac{9}{2} | + 3 | - 5 frac{1}{2} + frac{1}{2} | = \ = | frac{6}{2} - frac{9}{2} | + 3 | - frac{11}{2} + frac{1}{2} | = \ = | - frac{3}{2} | + 3 | - 5| = \ = frac{3}{2} + 3 times 5 = frac{3}{2} + frac{15}{1} = frac{3}{2} + frac{30}{2} = \ = frac{33}{2} = 16.5$
