Question

suppose there are three consecutive intergers.if two times the first is added to twice the middle, the results is 69 minus the largest number. what is the largest number?

Answer 1

3 consecutive means
x, x+1, x+2
OR
x, x-1, x-2

the equation based on givens and first equation is:

2(x) + 2(x+1) = 69 - (x+2)
4x + 2 = 67 - x
5x = 65
x = 13

so the largest would be x+2 or 15
