Answer:
(5x-1) (x+3) -(x-5) (5x+1)=40
5x(x+3) -1(x+3) -x(5x+1)+5(5x+1) =40
→5x²+15x-x-3-5x²-x+26x+5=40
→39x+2=40
→39x=40-2
→39x=38
→x=38/39

Answer:
x=27/25
Step-by-step explanation:
(5x+1)(x+3)-(x-5)(5x+1)=40
=(5x(x+3)+1(x+3))-(x(5x+1)-5(5x+1)=40
=(5x²+15+x+3)-(5x²+x-25x+5)=40
=5x²+15+x+3-5x²-x+25x-5=40
=15+3+25x-5=40
=18+25x-5=40
=13+25x=40
=25x=27
=x=27/25
