Given the equation:
22.5 + 7( n - 3.4)
Solve the equation.
Solution:
In order to solve the equation, we simply need to distribute 7 to each value inside the parenthesis, hence it must be taken to note that when distributing numbers, we must be conscious of the sign.
= 22.5 + 7(n -3.4)
= 22.5 + 7n - 23.8
=7n - 1.3
To solve for n, we transpose -1.3 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
7n = 1.3
divide both sides by 7 to determine the value of n.
7n/7 = 1.3/7
n= 0.18
Final answer:
Simplified form = 7n - 1.3
n = 0.18
