Please help me solve this problem please and thank you
Paha777 [63]

Answer:

y = 0

x = 8

Step-by-step explanation:

subtract second equation from first one

3x - 6y - (3x - y) = 24 - 24 the - sign in front of the parenthesis effects the inside expressions

3x - 6y - 3x + y = 24 - 24 add/subtract like terms

-5y = 0 and so y = 0

to find the value of x we can use this information

3x - y = 24 since y = 0

3x = 24 divide both sides by 3

x = 8

How many elements are in the set​ {x | x is an even prime​ number, x&lt;150}​?
Bond [772]

Answer:

The set {x | x is an even prime number, x<150} has 1 element.

Step-by-step explanation:

Prime Numbers: The numbers which have no factors other than 1 and the number itself are called prime numbers.  

Even Numbers are those numbers which are completely divisible by 2.

So, the only EVEN PRIME NUMBER = 2

Now, Set = {x | x is an even prime number, x<150}

So, the set has {2} as its only element.

Hence, the total elements in the set is 1.

Or, the set {x | x is an even prime number, x<150} has 1 element.
