First, you would simplify both sides of the equal signs, to do this, you would use the distributive property. 
21x + 3 = 21

Then, you would subtract 3 from both sides. 
21x = 18

Your final step would be to isolate the x, divide both sides by 21. 

Your answer would be x = 6/7

I hope this helps!

hoa [83]

Step-by-step explanation:

x + (x + 2) + (x + 4) + (x + 6) + (x + 8) = 135

5·x + 20 = 135

5·x = 115

x = 23

So the sequence is

23, 25, 27, 29, 31

The second number is 25.
