Two times the sum of a number and four increased by three is at most six less than the number.

Assign variables, and it should be like that:

2(x+4) + 3 < x - 6

x + 4 is the sum of the number and four,
Twice that is 2(x+4),
increased by 3 is +3,
At most means that it cannot be greater than,
And six less than the number will be x - 6.

Is that okay now?
