lets read the question in parts :

*Four times the sum of a number and two *

So 4 times what ?

4 times *sum of a number and two *

assume our number is x , So this above sentence is converted to

4*(x+2)

Second part of the question

**is nine less than five times the same number **

= 5x-9

So combing both half's of the statement

We get 4*(x+2) = 5x-9

That if you open up the brackets and simplify then reduces to

4x+8 = 5x - 9

5x-4x = 8+9

x= 17

Hope this helps !! break the sentence in two half's and build a relationship !
