Question

the difference between the two numbers is 23 and the sum is 129 find the numbers​

Answer 1

Step-by-step explanation:

Let first number be x

Seconds number be y

x+y=129

x-y=23

Addig both the equation

2x=152

x=152/2

x=76

Hence first no. is 76

We know

x+y=129

76+y=129

y=129-76

y=53

Hence second number is 53

Answer 2

Answer:

76 and 53

Step-by-step explanation:

Let the one no. - x

Other no. - y

x - y = 23.... 1)

x + y = 129..... 2)

A. T. Q

x - y + x + y = 23 + 129

2x = 152

x = 152/2

x = 76

...

x + y = 129

76 + y = 129

y = 129 - 76

y = 53

Numbers are 76 and 53.
