Question

1) x + y + 4x - 2y > 4;​

Answer 1

Ответ:

Х+у=4-х±2у=2

х=4-у-х+2у=2

-4+у+2у=2

3у=4+2

3у=6

у=6:3=2

х=4-у=4-2=2

ответ:у=2;х=2

Answer 2

To solve the inequality x + y + 4x - 2y > 4, we can combine like terms and simplify:

5x - y > 4

Now, let's isolate the variable x:

5x > y + 4

Divide both sides of the inequality by 5:

x > (y + 4) / 5

So, the solution to the inequality is x > (y + 4) / 5.
