Given the equation:
a + 1 - 2 =4
Determine the value of a.
Solution:
In order to determine the value of a, simply compute first 1 and -2, then transpose the answer to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
a + 1 - 2 =4
a - 1 =4
a = 4 + 1
a = 5
Final answer:
a = 5
