1.9z\leq 18.2-1.5
Subtract 1.5 from both sides.
1.9z\leq 16.7
Subtract 1.5 from 18.2 to get 16.7.
z\leq \frac{16.7}{1.9}
Divide both sides by 1.9. Since 1.9 is positive, the inequality direction remains the same.
z\leq \frac{167}{19}
Expand \frac{16.7}{1.9} by multiplying both numerator and the denominator by 10.
