-3-\left(6a+1\right)=-12
Multiply both sides of the equation by 3.
-3-6a-1=-12
To find the opposite of 6a+1, find the opposite of each term.
-4-6a=-12
Subtract 1 from -3 to get -4.
-6a=-12+4
Add 4 to both sides.
-6a=-8
Add -12 and 4 to get -8.
a=\frac{-8}{-6}
Divide both sides by -6.
a=\frac{4}{3}
Reduce the fraction \frac{-8}{-6} to lowest terms by extracting and canceling out -2.
