Solve 21-0.18xgeq0

$$21 - 0.18 x \geq 0$$

Solve for x

$$x\leq \frac{350}{3}$$

Solution Steps

Subtract 21 from both sides. Anything subtracted from zero gives its negation.

$$-0.18x\geq -21$$

Divide both sides by -0.18. Since -0.18 is negative, the inequality direction is changed.

$$x\leq \frac{-21}{-0.18}$$

Expand \frac{-21}{-0.18} by multiplying both numerator and the denominator by 100.

$$x\leq \frac{-2100}{-18}$$

Reduce the fraction \frac{-2100}{-18} to lowest terms by extracting and canceling out -6.

$$x\leq \frac{350}{3}$$
