Concept: Equivalent Equations
Concept: Equivalent Equations is a skill on Pengi from Section 1.1: Solving Simple Equations in Big Ideas Math, Advanced 2.
Key Concepts
Two equations are equivalent if they have the same solution set. When we apply the properties of equality to an equation, we create equivalent equations: if $a = b$, then $a + c = b + c$, $a c = b c$, $a \times c = b \times c$, and $a \div c = b \div c$ (where $c \neq 0$).
