Answer
The statement:“I solved a formula for one of its variables, so now I have a numerical value for that variable” does not make sense
Work Step by Step
One variable is not sufficient when there is more than one variable is there.
e.g.
\[\begin{align}
& x=10y+20z \\
& y=5x+10z \\
& z=x+y \\
\end{align}\]
In this case we need to solve all three variables to get the solution. One variable is not sufficient to solve this equation.
Hence, the provided statement does not make sense.
