3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)

3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6

$\frac{3x}{3}$ = $\frac{6}{3}$
3 and 3 cancels out
x = 2

Mathematics

x = -1/3

Step-by-step explanation:

x = [-6 +- squareRoot(36-4x9)] / 2 times (-6)

= -6/18 = -1/3

x-(-1/3) = 0 ---> x = -1/3
