Solve 1.20x+3>=13.50

$$1.20x+3 > =13.50$$

Solve for x

$$x>8.75$$

Solution Steps

Subtract 3 from both sides.

$$1.2x>13.5-3$$

Subtract 3 from 13.5 to get 10.5.

$$1.2x>10.5$$

Divide both sides by 1.2. Since 1.2 is positive, the inequality direction remains the same.

$$x>\frac{10.5}{1.2}$$

Expand \frac{10.5}{1.2} by multiplying both numerator and the denominator by 10.

$$x>\frac{105}{12}$$

Reduce the fraction \frac{105}{12} to lowest terms by extracting and canceling out 3.

$$x>\frac{35}{4}$$
