Question

The sum of three multiples of 7 is 84 what are the three multiples

Answer 1

Let one multiple of seven be x

So the other consecutive multiples of seven will be

x +7, x + 14

Therefore, x + x+7+x +14 = 84

3x + 21 = 84

3x = 63

x = 63/ 3

x = 21

so the three multiples of seven whose

sum is 84 are

1) 21

2) 28

3) 35

hope this helps you
