Hello!
To solve 2x+6>20, you'll first need to subtract. First, you'll need to subtract 6 from 20 (20-6). Now if the 6 was negative, you would need to add 6 to 20, but for this equation you'll subtract.
2x>14
Now you will need to divide both sides by 2. Once you've done that you'll have your answer of...
x>7
I hope this helps!
