What value of x is in the solution ser of 8x-6> 12+2x

I'm not sure what you're asking for.

If you're looking for a replacement for x that will make the statement true, we can just use 4.

8 * 4 - 6 > 12 + 2 * 4

32 - 6 > 12 + 8

26 > 20

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
