Question

What is the sum of three consecutive even numbers is 30?

Answer 1

here:

you can make an equation

x + ( x + 2) + (x + 4) = 30

then by combining like items you get

3x + 6 = 30

then solve

3x = 30 - 6 ; then 3x = 24 , and x = 8

so the three numbers are 8 ; 10 and 12.

Answer 2

8, 10, 12

A helpful equation:
x+x+1+x+2 = 30

Combine like terms
3x + 3 = 30

Subtract 3 from each side
3x = 27

Divide each side by to isolate x
x = 9

x = 9. However, 9 is not an even number. Let’s subtract 1 from 9 to get the first even number.

The first number is 8. The best two even numbers after 8 are 10 and 12.

8 + 10 + 12 = 30, thus this is the sequence.
