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
