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
