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
