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
