Given the numerical equation:
5x + 15 = 28
Solve for x.
Solution:
In order to solve for x, we simply need to transpose 15 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
5x + 15 = 28
5x = 28 -15
5x = 13
Divide both sides by 5 in order to determine the value of x.
5x/5 = 13/5
x = 13/5
Final answer:
x = 13/5
