Given the equation:
3x - 4 = 5
Solve for x.
Solution:
In order to solve for x, we simply needed to transpose - 4 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
3x - 4 = 5
3x = 5 + 4
3x = 9
Divide both sides by 3 in order to determine the value of x.
3x/3 = 9/3
x = 3
Final answer:
x = 3
