-10\times 45x\geq 9\left(3\times 10+5\right)
Multiply both sides of the equation by 90, the least common multiple of -9,10. Since 90 is positive, the inequality direction remains the same.
-450x\geq 9\left(3\times 10+5\right)
Multiply -10 and 45 to get -450.
-450x\geq 9\left(30+5\right)
Multiply 3 and 10 to get 30.
-450x\geq 9\times 35
Add 30 and 5 to get 35.
-450x\geq 315
Multiply 9 and 35 to get 315.
x\leq \frac{315}{-450}
Divide both sides by -450. Since -450 is negative, the inequality direction is changed.
x\leq -\frac{7}{10}
Reduce the fraction \frac{315}{-450} to lowest terms by extracting and canceling out 45.
