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
