Given the equation:
3x + 1 = 7
Solve for x.
Solution:
In order to solve for x, we simply need to transpose 1 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.
3x + 1 = 7
3x = 7 - 1
3x = 6
Divide both sides by 3 in order to determine the value of x.
3x/3 = 6/3
x = 2
Final answer:
x = 2
