Answer:

a) y = 2x - 3 and y = -2x - 3

Step-by-step explanation:

Here x is the larger number and y is the smaller number,

Given,

The difference between twice of x, and y is 3.

That is,

2x - y = 3\implies y = 2x - 3-----(1)

And, The sum of twice of x and y is –3,

2x + y = -3\implies y = -2x - 3-----(2)

Hence, from equation (1) and (2),

We can say that,

Option a is correct.

Determine the value of each expression.<br> i11=
Basile [38]

Answer:

11 * I

Unless you can tell me what I is equal to, I can't give you a number as an answer. Just take what ever I is equal to, an multiply it by 11. If the answer choices are equations rather than numbers, than just say 11 * 1.

If the question comes with any more information, please comment so I can give you a stronger answer.

Hope this helps! :)
