If x is the first of two consecutive integers expressed a sum of 20 in the second consecutive integers as an algebraic expression containing the variable X

Answer 1

X+X+1 = 20

2X = 19

X = 19/2 is not an integer

there are no two consecutive integers that sum to 20 or to any even number.

They always sum to an odd number

Maybe you meant the problem to be two consecutive odd or even integers, Then

x+x+2 = 20

2x = 20-2=18

x = 9, and x+2 = 11

9 and 11 are two consecutive odd numbers that sum to 20

an alternative method is 20/2 = 10, then go up 1 and down 1 to get 10+1 and 10-1 = 11 and 9 as the two consecutive odd integers summing to 20. 20/2 = x, x+ and -1 are the two integers
