Hi! i think for this you set up two equations.
x=y
4+x+y=50
you can solve by substitution!! hope it helpes
Answer:
1
Step-by-step explanation:
9 can't be the answer because 39 is not a prime number
3 can't be the answer because 33 is not a prime number
5 can't be the answer because 75, 35 and 15 are not prime numbers
1 is the answer because 71, 31 and 11 are all prime numbers
hope this helped!!
Let the three integers be x - 1 x and x + 1
(x - 1)(x + 1) = 6x + 6
x^2 - 1 = 6x + 6
x^2 - 6x - 7 = 0
(x - 7)(x + 1) = 0
x - 7 = 0
x = 7
x + 1 = 0
x = - 1
the solutions are (7,0) and (-1,0)
Answer:
x = 1
