1.3. Consider the equation:
2x+5=9
Below are three different ways that solve the equation, provide a
description of wha: each step is doing one each method.
1.3.1. Using substitution to show that 5 is not a solution to the equation.
Steps
Left-Hand-Side (LHS):
= 2(5)+5
= 10+5
= 15
Right-Hand-Side (RHS):
=9
