these are called inequalities. the first equation says that x is less than 6. since i am not exactly sure what you want to do with this equation i cannot give you more information for this problem. this is usually what an answer looks like to an inequality. the second problem reads x plus 2 is less than 7. subtract 2 from both sides of the equation just like you would if there was an equals sign and you get the answer x is less than 5 or x<5. when adding or subtracting inequalities you do the same as if it has an equals sign. if you have to use multiplication or division you have to change the inequality(if it is less than you make it greater than.
hope this helps

the first one means all numbers which are less than 6. the 2nd means all numbers which when increased by 2 are less than 7- that is, all numbers which are less than 5.

im learning this in school right now. so i'll try. You know that x<6 and x<5 (i simplified it) and when it's and, it has to agree to both. So it has to be a number between 5 and 6. like 5.5. Is that good? i tried

This is the intersection of two sets.
The fist set is all numbers less than 6
in the second set it is all numbers that satisfy x+2<7
Which can be solved to be x<5
So the intersection is x<5
