Question

The sum of two consecutive integers is 99. Find the integers

Answer 1

49,50

Explanation:

N+N+1=99 add the N's together

2N+1=99 subtract 1 from both sides

2N=98 divide 2 by 98

N=49 add the 1 from before

49+1=50

49,50 are the consecutive integers

Answer 2

48

Explanation:

The consecutive numbers will be x and x + 1. Then write out the equation 2x + 1 = 99

Collect like terms

2x = 99 - 1

2x= 98

divide both sides by 2

x = 49
