Question

If 2x-2x-1=4 then x is equal to
1. 27. 2. 1. 3. 8. 4. 54

Answer 1

then X is equal to 1

Answer 2

I have a doubt is the equation you have given as is 2x - 2 X - 1 = 4 or 2 x square - 2 X - 1 = 4

if it is 2x - 2x - 1 = 24

then the 2 x-2 x cut down

does the result came out is

-1 = 4

if I consider it

2xsquare -2x-1 =4

then the above image will help you
