Solve 0.8x+1.5<4.7

$$0.8 x + 1.5 < 4.7$$

Solve for x

$$x<4$$

Solution Steps

Subtract 1.5 from both sides.

$$0.8x<4.7-1.5$$

Subtract 1.5 from 4.7 to get 3.2.

$$0.8x<3.2$$

Divide both sides by 0.8. Since 0.8 is positive, the inequality direction remains the same.

$$x<\frac{3.2}{0.8}$$

Expand \frac{3.2}{0.8} by multiplying both numerator and the denominator by 10.

$$x<\frac{32}{8}$$

Divide 32 by 8 to get 4.

$$x<4$$
