Let us consider a variable x.
and now we take a equation in terms of the variable x as follows:
[tex]2x-25=-75[/tex]
First step:
We first add both side of the equation by 25.
i.e. the first step involves the process of addition.
[tex]2x=-75+25\\\\i.e.\\\\2x=-50[/tex]
Second step:
Now we divide both side of the equation by 2 to obtain:
i.e. this step involves the process of division.
[tex]x=\dfrac{-50}{2}\\\\i.e.\\\\x=-25[/tex]
