Question

Find 2 numbers, if their sum is -7 and their difference is 14.

Answer 1

Answer:

Bro the Ans is X+y=-7

x-y=14

therefore,X=7/2

y=2

Answer 2

Given :

• Sum of two numbers = -7
• Difference of two numbers = 14

To find :

Two numbers

Let :

• First number = x
• Second number = y

Solution :

According to question,

Sum of two numbers = -7

➝ x + y = -7

➝ x = -7 - y. equation 1

________________________________

According to question,

Difference of two numbers = 14

➝ x - y = 14

On putting value of x from equation 1 into above equation we get;

➝ ( -7-y ) - y = 14

➝ -2y = 14 + 7

➝ -2y = 21

➝ 2y = -21

➝ y = (-21)/2

➝ y = - 10.5

________________________________

Put value of y in equation 1

➝ x = -7 - (-10.5)

➝ x = -7 + 10.5

➝ x = 3.5

ANSWER :

The required number are 3.5 , (-10.5)
