Answer 2

Answer:

Let the two numbers be x and y

According to question

x+y=23...(1)

x*y=120 ...(2)

now substitute value of x from eq(1) to eq.(2)

(23-y)*y=120

23y-y²=120

0=y²-23y+120

0=y²-15y-8y+120

0=y(y-15)-8(y-15)

0=(y-15)(y-8)

Either y=15 or 8....

x=23-15=8

or x=23-8=15

So the two numbers are 15 and 8...
