Question

The sum of three consecutive integers is 267. What is the largest integer

Answer 1

X= largest integer X-1=next integer X-2=lowest integer x + x-1 + x-2 = 267 3x-3=267 3x=267+3 3x=270 X=270÷3 X=90 Now substitute x + x-1 + x-2 = 267 90+ (90-1)+(90-2)=267 90+89+88=267 So largest integer is 90
