9(x+3)=3(3x+6)+9 how many solutions?
Slav-nsk [51]

♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️

9(x +3) = 3(3x + 6) + 9

9x + 27 = 9x + 18 + 9

9x + 27 = 9x + 27

The two sides of this equation are exactly the same, so the above equation holds for any value of x , <em>thus we have infinite solution for it.</em>

grandymaker [24]

Answer:

11 calls
