Find three consecutive integers whose sum in 36
ratelena [41]
ANSWER: 11, 12, 13

3 consecutive integers:
x \\ x + 1 \\ x + 2
"Sum" means Add

x + x + 1 + x + 2 = 36
Combine like-terms
3x + 3 = 36
Solve for X
3x + 3 = 36 \\
Subtract 3 from both sides
3x = 33
Divide by 3 on both sides
x = 11
11 + 1 = 12
11 + 2 = 13
