Given the numerical statement:

3(3x - 2) = 8 

prove x =7/6

Solution:

In order to prove the numerical equation, we simply need to distribute 3 to each value inside the parenthesis.

3(3x - 2) = 8 

9x - 6 = 8

Now we need to transpose -6 on the other side of the equation, hence it must be taken to note that when transposing a number, the sign changes.

9x = 8 + 6

9x = 14

DIvide both sides by 9 in order to get the value of x.

9x/9 = 14/9

x = 14/9 

Final answer:

x is not equal to 7/6 based on the solution that was computed, hence the value of x is equal to 14/9
