Question

прошу помогите ! решить .при каком значении а значение выражения а-16 больше .чем значение выражения 22-а .на 4 предмет по матиматик за 5 кл

Answer 1

Напишу то же самое.

a - 16 = 22 - a + 4
a - 16 - 22 + a - 4 = 0
2a = 42
a = 21

если a - 16 = 26 - a

то мы берём не 21, а 23 так как теперь разница должна быть не 2, а 4

проверяем:

26 - 23 = 3
23 - 16 = 7
7 - 3 = 4

Ответ: a = 23

Answer 2

Solving the Expression for the Value of 'a'

To solve for the value of 'a' in the expression a - 16 > 22 - a + 4, we can follow these steps:

1. Combine Like Terms: Combine the constants and the 'a' terms on each side of the inequality. 2. Isolate the Variable: Isolate the variable 'a' on one side of the inequality. 3. Solve for 'a': Solve for the value of 'a' that satisfies the inequality.

Step 1: Combine Like Terms

The given inequality is a - 16 > 22 - a + 4.

Step 2: Isolate the Variable

To isolate the variable 'a', we can add 'a' to both sides of the inequality and add 16 to both sides.

Step 3: Solve for 'a'

After isolating 'a', we can solve for its value.

a - 16 + a > 22 + 4

2a - 16 > 26

2a > 26 + 16

2a > 42

a > 42 / 2

a > 21

So, the value of 'a' in the given expression is a > 21.
