The sum of two numbers exceeds their product by one.Their difference is equal to their products less five .Find the two numbers
Ludmilka [50]

Answer:

1 and 3

Step-by-step explanation:

If the two numbers are x and y, then:

x + y = xy + 1

x − y = xy − 5

Subtract the two equations:

(x + y) − (x − y) = (xy + 1) − (xy − 5)

x + y − x + y = xy + 1 − xy + 5

2y = 6

y = 3

Solve for x:

x + 3 = 3x + 1

2 = 2x

x = 1

The numbers are 1 and 3.

melisa1 [442]

Answer:

AB = 35

Step-by-step explanation:

For the value of variable z....;

;Perimetre = 132

; 132 = 2(4z + 3) + 2(5z)

; 132 = 8z + 6 + 10z

; 132 - 6 = 8z + 10z

; 126 = 18z

;the value of...z = 7

Therefore the value of length AB;

AB = 5z...then substitute the value of z into the length of AB

; AB = 5(7)

;AB = 35
