Answer: x=2
57+x=25x
subtract x from both sides
57+x-x=25x-x
57=24x
divide by 24 on both sides
57÷24=24x÷24
x=2.375
I hope this is good enough:

Answer:
(2a+3 ) (a-4 )=0
Step-by-step explanation:
2a^2 + 8a - 15 = 3a - 3
Subtract 3a from each side
2a^2 + 8a-3a - 15 = 3a-3a - 3
2a^2 + 5a - 15 = - 3
Add 3 to each side
2a^2 + 5a - 15+3 = 3 - 3
2a^2 -5a -12=0
(2a+3 ) (a-4 )=0 These are the factors
Answer:(2,-16) is the correct answer..
