1) Distribute
2x + 28x + 21
2) Combine like terms
30x + 21
Since there are no more like terms, 30x and 21 cannot be combined. Therefore, the answer is 30x+ 21
Keep Change Flip!!!
Keep: the first fraction 5 or 5/1
Change: Division sign to multiplication sign
Flip (reciprocal): the second fraction
So you get 5/1*9/2= 45/2 which simplified to 22 1/2

To find the solution to the equation, we have to rearrange the equation to make 
the subject:
⇒ 
[Subtracting 2 from both sides]
⇒ 
⇒ 
[Subtracting 
from each side]
⇒ 
⇒ 
[Diving both sides by 213]

By definition of absolute value we have two equalities:
2x + 1 = 10
2x + 1 = -10
For 2x + 1 = 10:
2x + 1 = 10
2x = 10-1
2x = 9
x = 9/2
For 2x + 1 = -10:
2x + 1 = -10
2x = -10-1
2x = -11
x = -11 / 2
Answer:
{-11/2, 9/2}
