Given the equation:
2x + 8 = 15
Solve for x.
Solution:
In order to solve for x, we simply need to transpose 8 to the other side of the equation hence it must be taken to note that in transposing a number the sign changes.
2x + 8 = 15
2x + 8 = 15 - 8
2x = 7
Divide both sides by 2 in order to cancel outleaving behind 2.
2x/2 = 7/2
x = 7/2
Final answer:
x = 7/2
