Question

. The sum of two numbers is 87. If one number exceeds the other by 27 , find the numbers.​

Answer 1

Answer:

30 and 57

Step-by-step explanation:

Let first number = x

Let second number = x + 27

According to question

x + x + 27 = 87

2x = 87 - 27

2x = 60

x = 30

So, numbers are 30 and 57

Answer 2

Answer:

y=30, x=57

Step-by-step explanation:

Let the first number be x

second number be y

x+y=87 -----1

x=y+27

x-y=27-----2

By using elimination method

Adding eq 1 and 2

x+y=87

x-y=27

 2x  = 114

Transposing 2  

x=114/2

x=57

x+y=87

57+y=87

transposing 57

y=87-57

y=30
