(x - 9)(x + 9) is incorrect answer

x^2 - 18x + 81
= (x - 9)^2
= (x - 9)(x - 9)

Answer

Write two equations so that each have variables on both sides and a solution of 1/2
AlladinOne [14]
The solution will be:

x=\frac{1}{2}

we can start here and just modify this, for example: add x to both sides:

2x=\frac{1}{2}+x

this is one such equation!


and further let's add 5 to both sides


2x+5=5\frac{1}{2} +x
and another such equation!
