Answer:

28

Step-by-step explanation:

Let the first even number be x

2nd even number = x + 2

3rd even number = (x +2) + 2 = x + 4

Their sum = 90

X + x + 2 + x + 4 = 90

Collect like terms

3x + 6 = 90

3x = 90-6

3x = 84

Divide both sides by 3

3x/3 = 84/3

X =28

Therefore the smallest even number is 28.
