Solving equations with one variable – Word problem
1) The sum of three consecutive integers is two less than 35. Find all the three consecutive numbers
10, 11 and 12
19, 20 and 21
13, 14 and 15
16, 17 and 18
1/10
Solution
Answer:
10, 11 and 12
Explanation:
Let the first consecutive numbers be x
Let the second consecutive numbers be x + 1
Let the third consecutive numbers be x + 2
x + (x + 1) + (x + 2) = 35 – 2
3x + 3 = 33
3x = 30
x = 10, the numbers are 10, 11 and 12
