Transitive Property of Equality

Rule

Transitive Property of Equality

For all real numbers, if two numbers are equal to the same number, then they are equal to each other.

If a=ba=b and b=c,b=c, then a=c.a=c.

This property can be used together with other Properties of Equality to solve equations. {x=5y305y30=20x=20\begin{gathered} \begin{cases} x = {\color{#0000FF}{5y-30}} \\ {\color{#0000FF}{5y-30}} = 20 \end{cases} \quad \Rightarrow \quad \begin{aligned} x &=20 \end{aligned} \end{gathered} The Transitive Property of Equality also holds true if a,a, b,b, and cc are complex numbers.
