Given:
15x + 21 = 8
Determine the solution of the given equation.
Solution: In order to determine the solution of the given equation, we simply need to transpose 21 to the other side of the equation, hence it must be taken to note that in transposing numbers, the sign changes.
15x + 21 = 8
15x = 8 - 21
15x = -13
DIvide both sides by 15 in order to cancel out 15x, leaving behind x.
15x/15 = -13/15
x = -13/15
Final answer:
x = -13/15
