Question

((ОЧЕНЬ СРОЧНО))При каком значении переменой y значение выражения 3y + 9 на8 больше значения выражения 7-4y?

Answer 1

3у+9-(7-4у)=8
3у+9-7+4у=8
7у=10
у=10\7

Answer 2

Understanding the Inequality

To determine the meaning of the variable y in the given inequality, we can start by solving the inequality and then interpreting the result.

The given inequality is: 3y + 9 > 7 - 4y

Solving the Inequality

Let's solve the inequality step by step:

1. Combine Like Terms: Add 4y to both sides of the inequality to get the variable terms on one side: 3y + 4y + 9 > 7

2. Combine Like Terms: Combine the variable terms: 7y + 9 > 7

3. Isolate the Variable: Subtract 9 from both sides of the inequality: 7y > -2

4. Solve for y: Finally, divide both sides by 7 to solve for y: y > -2/7

Interpreting the Result

The inequality y > -2/7 indicates that the value of y must be greater than -2/7 for the given expression 3y + 9 to be greater than 7 - 4y.

Therefore, the meaning of the variable y in the given inequality is that it must be greater than -2/7 for the inequality to hold true.
