200a+5100-170a\leq 5400
Use the distributive property to multiply 170 by 30-a.
30a+5100\leq 5400
Combine 200a and -170a to get 30a.
30a\leq 5400-5100
Subtract 5100 from both sides.
30a\leq 300
Subtract 5100 from 5400 to get 300.
a\leq \frac{300}{30}
Divide both sides by 30. Since 30 is positive, the inequality direction remains the same.
a\leq 10
Divide 300 by 30 to get 10.
