Given:
3x + 2x - 6 = 24
Determine the mistake.
Solution:
In order to determine the mistake, we remove 24 and equate the equation to 0, since it is stated that a mistake was made so it is probably the constant 24.
3x + 2x -6 = 0
Transpose -6 on the other side of the equation, note that when transposing a number, the sign changes.
3x + 2x = 6
5x = 6
x = 5/6
Final answer:
x = 5/6
