    does that mean you can get the answer in "one step"?

    when you only have to do one step to solve it i think

    ok so it is something like \[x+5=9\]i guess you are supposed to the the "opposite" of \(5\) is \(-5\) so we can solve via \[x+5-5=9-5\\ x=4\]

    or if you have \[x-4=7\] then the "opposite" of \(-4\) is \(4\) so \[x-4+4=7+4\\ x=11\]

    maybe include \[2x=10\] the "opposite" of multiplying by 2 is dividing by 2, so \[2x=10\\ \frac{2x}{2}=\frac{10}{2}\\ x=5\]
