You meant:

I can't; help me.

5x-2y = 14
2x+2y = 14
------------- add the two equations
4y = 28

I expect that you can handle it from here, eh?

Oops. adding the equations eliminates y.

7x = 28

If a die is cast ,what is the probability of getting a prime number

There are six possible outcomes when a die is cast, which are numbers 1 through 6. Of these six possible outcomes, there are three prime numbers: 2, 3, and 5. Therefore, the probability of getting a prime number is 3/6 or 1/2, which simplifies to 0.5 or 50%.

5x-2y=14and 2x plus 2y=14

7x - 4y=28

To solve the simultaneous equations 5x - 2y = 14 and 2x + 2y = 14:

1. Rearrange the second equation to solve for y:
2x + 2y = 14
2y = 14 - 2x
y = 7 - x

2. Substitute this expression for y into the first equation:
5x - 2y = 14
5x - 2(7 - x) = 14
5x - 14 + 2x = 14
7x = 28

3. Solve for x:
7x = 28
x = 4

4. Substitute this value of x back into either equation to solve for y:
2x + 2y = 14
2(4) + 2y = 14
8 + 2y = 14
2y = 6
y = 3

Therefore, the solution to the simultaneous equations 5x - 2y = 14 and 2x + 2y = 14 is x = 4 and y = 3.
