4 + b > 20 but the less than sign is underlined

Are you solving for b?
4 + b ≥ 20
Subtract 4 from both sides. This doesn't change the direction of the ≥ (greater than or equal) sign.
b ≥ 20 - 4
b ≥ 16
Remember to read this as b is *greater than or equal to" 16.

A bit strange this one. Actually the sign is greater than not less, and the underline means "greater than or equal to".
So the equation reads 4 + b is greater than or equal to 20.
I would rewrite that to read 4+b=20 Therefore, moving the 4 from the left to the right and changing it's sign, b=20-4 equals 16.
Therefore b must be 16 or more written as b>16 (but replace my > symbol with the greater than or equal to.

subtract 4 from each side which gives you b>16 and the less than sign is underlined

you would subtract 4 from both sides to get:
b>16
except with the less than sign underlined making it less than or equal to.

that means 4+ b > 20 with the line under the less than sign is less than or equal to 20 hope that made it easier to figure out

b>=16 since it means greater than or equal to 20..
b>=20-4, by trasposing +4 to the other side
b>=16

You have to subtract 4 from 20, then write it
b > 16. And that's your answer.

this is a ray on a number line you put a dot on 16 with a
line going backward to zero in to the neg.
with a < on the end of it . This shows that 16 and everything
less than 16 makes this statement true.

4+b>20
4-4+b>20-4
4-4 cancels out
b>16
