Question

The sum of twice a number and 23 is 81​

Answer 1

Answer:

Let one number of the given pair be x

The other number is twice the number of sum

The sum of two numbers is 81

x+2(81)=81

x+162=81

x=81-162

x=-81

The pair of numbers are -81 and 162

Answer 2

Answer:

29.5

Step-by-step explanation:

Let us assume the number to be x

So twice x is 2x

So, the equation would be,

2x+23=82

So, by transposition method,

2x=82-23

2x=59

So, x=59/2

Therefore, x=29.5

So, the answer is 29.5
