Question

If X + Y equal to 12 and xy equal to 35 find the value of x minus y solve

Answer 1

Answer:

2 or -2

Step-by-step explanation:

xy=35

y=35/x

x+y=12

x+35/x=12

x2+35/x=12

x2+35=12x

x2-12x+35=0

x2-5x-7x+35=0

x(x-5)-7(x-5)=0

(x-7)(x-5)=0

x=7;5

y=35/x

y=5;7

x-y=7-5 or 5-7

x-y=2 or -2

Answer 2

Answer:

THE ANSWER IS 2

Step-by-step explanation:

BECAUSE FIRSTLY WE TAKE X+Y

WE CAN REPLACE 7 TO THE PLACE OF X AND 5 TO THE PLACE OF Y SO NOW WE ADD THEM THE ANSWER IS 12

THEN WE TAKE XY =SAME FORMULA X=7 & 5 = Y

THEN WE MULTIPLY BOTH THE ANSWER IS 35

AT LAST WE SUBTRACT THEM BOTH =X-Y(7-5) = 2
