Question

the sum of two number is 2. if there difference is 20,find the answer

Answer 1

ANSWER :-

11 AND - 9

EXPLANATION :-

Let’s assume the two numbers to be x and y

Then according to the given conditions, we have

Then according to the given conditions, we havex+y=2 … (i) and

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22⇒x=11

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22⇒x=11On substituting the value of x in (i), we get

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22⇒x=11On substituting the value of x in (i), we get11+y=2

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22⇒x=11On substituting the value of x in (i), we get11+y=2⇒y=2−11

Then according to the given conditions, we havex+y=2 … (i) andx−y=20 … (ii)Now, adding (i) and (ii) we get2x=22⇒x=11On substituting the value of x in (i), we get11+y=2⇒y=2−11⇒y=−9

Answer 2

Answer:

11 and -9

Step-by-step explanation:

Let’s assume the two numbers to be x and y

Then according to the given conditions, we have

x + y = 2 … (i) and

x – y = 20 … (ii)

Now, adding (i) and (ii) we get

2x = 22

x = 11

On substituting the value of x in (i), we get

11 + y = 2

y = 2 – 11

y = -9

Therefore, the two numbers are 11 and -9.
