Answer:
x = -8
Step-by-step explanation:
4( 3x +5 ) - 3 = 9x -7
Distribute
12x +20 -3 = 9x -7
Combine like terms
12x+17 = 9x-7
Subtract 9x from each side
12x-9x +17 = 9x-9x-7
3x +17 = -7
Subtract 17 from each side
3x+17-17 = -7-17
3x = -24
Divide each side by 3
3x/3 = -24/3
x = -8
Add all the numbers and divide by how many there are.
The mean is 38.9
