Answer: All Numbers Are Real Solutions (Note - Have An Amazing Day! :)
Comment If I'm Wrong!
Step-by-step explanation:
4(3x+5)=5(x+4)+7x
4(3x+5)=5(x+4)+7x
(4)(3x)+(4)(5)=(5)(x)+(5)(4)+7x
12x+20=5x+20+7x
12x+20=(5x+7x)+(20)
12x+20=12x+20
12x+20=12x+20
12x+20−12x=12x+20−12x
20=20
20−20=20−20
0=0
Answer: All real numbers are solutions
