-3\left(6x+1\right)=2
Multiply both sides of the equation by 6, the least common multiple of 2,3.
-18x-3=2
Use the distributive property to multiply -3 by 6x+1.
-18x=2+3
Add 3 to both sides.
-18x=5
Add 2 and 3 to get 5.
x=\frac{5}{-18}
Divide both sides by -18.
x=-\frac{5}{18}
Fraction \frac{5}{-18} can be rewritten as -\frac{5}{18} by extracting the negative sign.
