Answer:
2x+9 = 27 => 2x =18 => x =9
5y = 125 => y = 25
Answer:
3 • (2x - 7) - (x + 4) = 0
then do 3.1 Pull out like factors :
5x - 25 = 5 • (x - 5)
5 • (x - 5) = 0
4.2 Solve : x-5 = 0
Add 5 to both sides of the equation :
x = 5
Step-by-step explanation:
Sorry I didn't read that correct!! If you aren't sure how to do the division, just keep subtracting 4.25 from $20 until you can't anymore!
