3\left(a+1\right)-2\left(2a+1\right)=24
Multiply both sides of the equation by 6, the least common multiple of 2,3.
3a+3-2\left(2a+1\right)=24
Use the distributive property to multiply 3 by a+1.
3a+3-4a-2=24
Use the distributive property to multiply -2 by 2a+1.
-a+3-2=24
Combine 3a and -4a to get -a.
-a+1=24
Subtract 2 from 3 to get 1.
-a=24-1
Subtract 1 from both sides.
-a=23
Subtract 1 from 24 to get 23.
a=-23
Multiply both sides by -1.
