Answer:

x = 5

Step-by-step explanation:

1. Expand

    8x - 5x + 5 = 20

2. Simplify

    3x + 5 = 20

3. Subtract 5 from both sides

    3x = 20 - 5

4. Simplify

    3x = 15

5. Divide both sides by 3

    x = 15/3

6. Simplify

    x = 5

Answer:

No there is not

Step-by-step explanation:

Combine like terms so 3x+2x= 5x so it would leave you with 5x+2  In the problems there is a 5x in both and a 2 in one and a 5 in the other so they could not be possible to solve because what ever you do 5x+5 will always be 3 more then the other.

QR = PR - PQ

QR = 13y + 25 - (8y + 5)
QR = 13y + 25 - 8y - 5
