1. The solution for the given equation is a = -5.

   What is an equation?

   • An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.

   To find the solution to the given equation:

   Negative (5 minus (a + 1)) = 9 minus (5 minus (2a minus 3)) can be expressed mathematically as follows.

   • – (5 – (a + 1)) = 9 – (5 – (2a – 3))

   Using the principle of PEMDAS, all the parenthesis values are first solved.

   • – (5 – a – 1) = 9 – (5 – 2a + 3)
   • -5 + a + 1 = 9 – 5 + 2a – 3

   Collect like terms:

   • -5 + 1 – 9 + 5 + 3 = 2a – a
   • -5 = a

   That is a = -5.

   Therefore, the solution for the given equation is a = -5.
