Question

the sum of two number is 25 and their difference is 33 find their product​

Answer 1

Answer: -116

Step-by-step explanation:

•Let the two number be x and y, where x>y

•ATQ, x+y=25 ---(1)

x-y=33 ---(2)

•Adding (1) and (2)

(elimination method)

x+y=25

x-y=33

----------

2x=58

x=29

•On substituting value of x in (1)

29+y=25

y=-4

•Their product: 29 X -4

=-116

Answer 2

Answer:

-116

Step-by-step explanation:

Let the two no. be x and y

x+y=25 (equation 1)

x-y=33 (equation 2)

From eq 1

x=25-y

PTV of x in eq 2

25-y-y=33

25-2y=33

-2y=33-25

-2y=8

y=-4

PTV of y in eq 1

x+(-4)=25

x=25+4

x=29

product= 29×(-4)

=-116
