1. Solving a formula for one of its variables mean there are more than oone variable.

We cannot solve a variable from a single multivariable equation

$⇒2x+4y=9$

if we solve eqither $x$ or $y$ we wolud not get a numerical value.

2. Statement makes sense.

Let us take $2x+4y=9$

Solving for $x$ and $y$ gives

$x=\frac{9-4y}{2}$      $y=\frac{9-2x}{4}$

3.  Statement makes sense.

By solving for a variable, we can use that value of variable (substitute) in later steps of a problem.

4. Makes sense.

Let us take an example

Plug $x=3$ in $\left(1\right)$
