Given the numerical equation:
45n = 1 (4n + 9)
Evaluate.
Solution:
In order to evaluate the given numerical equation, we simply need to distribute 1 to each value inside the parenthesis first.
45n = 1 ( 4n + 9 )
45n = 4n + 9
Transpose 4n to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
45n - 4n = 9
41n = 9
Divide both sides by 41 to cancel out 41n, leaving behind n.
41n/41 = 9/41
n = 9/41
Final answer:
n = 9/41
