Step-by-step explanation:
If you know how to do an equation like: 5x - 3 = 21
Or something formatted like that, its the exact same thing, only there's a different sign. So I believe the first one would be:
x + 3 < 5
- 3 -3
x = 2
But I just learnt how to do this so let me know if it works :)
Also! If the number after the sign's (such as < or >) sign changes (such as -3 becomes 3 or 3 becomes -3. or even when -3 becomes 1) then you swap the sign ( < becomes > and visa versa) But this only works if it changes due to a multiplication or division. Example:
-3x > 3
(divide by -3)
x < -1
I swapped the sign. Make sense?? Let me know if it doesnt and I'll clarify
