26\alpha +7000-35\alpha =6280
Use the distributive property to multiply 35 by 200-\alpha .
-9\alpha +7000=6280
Combine 26\alpha and -35\alpha to get -9\alpha .
-9\alpha =6280-7000
Subtract 7000 from both sides.
-9\alpha =-720
Subtract 7000 from 6280 to get -720.
\alpha =\frac{-720}{-9}
Divide both sides by -9.
\alpha =80
Divide -720 by -9 to get 80.
