Solve 4 + |x| = 4
Solving Absolute Value Equations:
An absolute value equation is an equation that contains the variable within absolute value bars. We can solve these types of equations using the rule that if |C| = m, then C = m or C = -m. This rule allows us to get the variable out of the absolute value bars in order to solve for it.
Answer and Explanation:
Solving the absolute value equation 4 + |x| = 4 gives x = 0.
To solve this equation, we will use our absolute value rule. We start by isolating the...
