To solve the equation -9 - (-5) = a, you need to follow a few steps.
Step 1: Start by simplifying the expression inside the parentheses. When you have a negative sign in front of parentheses, you can distribute that negative sign to each term inside the parentheses. So, -(-5) becomes +5.
Step 2: Rewrite the equation with the simplified expression. -9 + 5 = a.
Step 3: Perform the addition. -9 + 5 equals -4. Therefore, a = -4.
So, the value of a in the equation -9 - (-5) = a is -4.
