Given:

5x + 9/2 = 12

Solve for x.

Solution:

In order to solve for x, transpose 9/2 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

5x + 9/2 = 12

5x = 12 - 9/2

12 can be written as 24/2.

5x = 24/2 - 9/2

5x = 15/2

Divide both sides by 5 in order to determine the value of x.

5x/5 = (15/2)/5

x = 15/10

x = 3/2

Final answer:

x = 3/2
