6\alpha -2=\alpha +8
Use the distributive property to multiply 2 by 3\alpha -1.
6\alpha -2-\alpha =8
Subtract \alpha from both sides.
5\alpha -2=8
Combine 6\alpha and -\alpha to get 5\alpha .
5\alpha =8+2
Add 2 to both sides.
5\alpha =10
Add 8 and 2 to get 10.
\alpha =\frac{10}{5}
Divide both sides by 5.
\alpha =2
Divide 10 by 5 to get 2.
