Question

What two consecutive numbers add to 257?

Answer 1

Let 'x' be the first number
Since they are consecutive numbers then we let 'x+1' be the 2nd number
Since their sum would be 257 then you'll have the equation as:
x + (x+1) = 257
Solve for x

Answer 2

So x is 256?

Answer 3

Nope.
Solve for x from the derived equation that we have which is
x + (x+1) = 257
Removing the parenthesis it will be:
x + x + 1 = 257
Transpose 1 to the right
x + x = 257 - 1
Combine like terms
2x = 256
Solve for x

Answer 4

128???

Answer 5

yep. that would be the first number
the second number would be
x+1

Answer 6

Is it right? Because 2x128= 256

Answer 7

What do u mean that the second number is x+1??

Answer 8

since you are looking for 2 numbers which happened to be consecutive and we designate them as
'x' - being the 1st number
'x+1' - the 2nd number
then you'll have it as
x = 128
x + 1 = 129
Therefore the two consecutive numbers that would add up to 257 would be 128 and 129
