Different ways to solve equations
We have 4 ways of solving one-step equations: Adding, Substracting, multiplication and division.
If we add the same number to both sides of an equation, both sides will remain equal.
Example
$$x=y$$
$$x+z=y+z$$
If we subtract the same number from both sides of an equation, both sides will remain equal.
Example
$$x=y$$
$$x-z=y-z$$
If we divide both sides of an equation by the same number, both sides will remain equal.
Example
$$x=y$$
$$x\div z=y\div z$$
If we multiply both sides of an equation by the same number, both sides will remain equal.
$$x=y$$
$$x\cdot z=y\cdot z $$
