Solve -1.2b-5.3geq1.9

$$- 1.2 b - 5.3 \geq 1.9$$

Solve for b

$$b\leq -6$$

Solution Steps

Add 5.3 to both sides.

$$-1.2b\geq 1.9+5.3$$

Add 1.9 and 5.3 to get 7.2.

$$-1.2b\geq 7.2$$

Divide both sides by -1.2. Since -1.2 is negative, the inequality direction is changed.

$$b\leq \frac{7.2}{-1.2}$$

Expand \frac{7.2}{-1.2} by multiplying both numerator and the denominator by 10.

$$b\leq \frac{72}{-12}$$

Divide 72 by -12 to get -6.

$$b\leq -6$$
