Hi
Just told you : first know by heart remarkable identities !
Then apply :
4x²-12x = -9
4x²-12x +9 =0
(2x-3)² = 0
(2x-3) (2x-3) = 0
Now you have a double solution :
2x-3 = 0
and 2x -3 = 0
I let you try !

i hope this helps :)
Let, the number = x
Then, 2x + 3 = 4x - 5
2x - 4x = -5 - 3
-2x = -8
x = 8/2
x = 4
In short, the number would be: 4
Hope this helps!
