The Multiplication Property of Equality states that multiplying each side of an equation by the same number yields an equivalent equation.

This is one of the Properties of Equality that can be used when solving equations.

To isolate the variable, the division by $4$ can be eliminated by multiplying both sides of the equation by $4,$ since multiplication is the inverse operation of division.

The Multiplication Property of Equality also holds true if $a,$ $b,$ and $c$ are complex numbers.
