Answer:
3x + 4 > 22 // x = 7 or up
Step-by-step explanation:
I assume this is a 'Take words and put into an equation' so here
'Three times a number'
Lets say a number is represented by x, it'd be 3x
'Four more than'
That's addition, adding onto the previous number it would be 3x + 4
Finally the 'Greater than 22' is > this sign
3x + 4 > 22
If you need to solve for x, then whatever is multiplied by 3 then added by 4 must be more than 22. It can really be anything 7 and up. 3x5 is 15, add 4 and it's 19, which is less than 22. 3x6 is 18, add 4 and its 22, that's equal to it, not greater than. 3x7 is 21, add 4 and it's 25. Anything further along with that will be greater than 22.
