Пошаговое объяснение:

28-14:7+9*(28-14):7+9=28-14:7+9*14:7+9=28-14:7+9*2+9=28-2+18+9=26+18+9=44+9=53

Answer 2

To solve the expression, follow the order of operations (PEMDAS: Parentheses, Exponents, Multiplication and Division, Addition and Subtraction):

$28 - 14$ equals $14$.

$9 \times 14$ equals $126$.

Now, let's rewrite the expression:

$14 : 7 + 126 : 7 + 9$

$14 \div 7$ equals $2$.

$126 \div 7$ equals $18$.

Now the expression looks like:

$2 + 18 + 9$

$2 + 18$ equals $20$.

Finally:

$20 + 9 = 29$

So, $28 - 14 : 7 + 9 \times (28 - 14) : 7 + 9$ equals $29$.
