3\left(a+1\right)-2\left(4a+1\right)=24
Multiply both sides of the equation by 6, the least common multiple of 2,3.
3a+3-2\left(4a+1\right)=24
Use the distributive property to multiply 3 by a+1.
3a+3-8a-2=24
Use the distributive property to multiply -2 by 4a+1.
-5a+3-2=24
Combine 3a and -8a to get -5a.
-5a+1=24
Subtract 2 from 3 to get 1.
-5a=24-1
Subtract 1 from both sides.
-5a=23
Subtract 1 from 24 to get 23.
a=\frac{23}{-5}
Divide both sides by -5.
a=-\frac{23}{5}
Fraction \frac{23}{-5} can be rewritten as -\frac{23}{5} by extracting the negative sign.
