Given the numerical equation:

2x + 2 = 9

Determine the value of x.

Solution:

In order to determine the value of x, we simply transpose first 2 to the other side of the equation, hence it must be taken to note that in transposing a number, the sign changes.

2x + 2 = 9

2x = 9 - 2

2x = 7

Divide both sides by 2 in order to find the value of x.

2x/2 =7/2

x = 7/2

Final answer:

x = 7/2
