3a-12+3\left(4-a\right)+2a-1=3
Use the distributive property to multiply 3 by a-4.
3a-12+12-3a+2a-1=3
Use the distributive property to multiply 3 by 4-a.
3a-3a+2a-1=3
Add -12 and 12 to get 0.
2a-1=3
Combine 3a and -3a to get 0.
2a=3+1
Add 1 to both sides.
2a=4
Add 3 and 1 to get 4.
a=\frac{4}{2}
Divide both sides by 2.
a=2
Divide 4 by 2 to get 2.
