Solve 4-0.3x-0.4x=2.4-0.2x

$$4-0.3x-0.4x=2.4-0.2x$$

Solve for x

$$x=3.2$$

Steps for Solving Linear Equation

Combine -0.3x and -0.4x to get -0.7x.

$$4-0.7x=2.4-0.2x$$

Add 0.2x to both sides.

$$4-0.7x+0.2x=2.4$$

Combine -0.7x and 0.2x to get -0.5x.

$$4-0.5x=2.4$$

Subtract 4 from both sides.

$$-0.5x=2.4-4$$

Subtract 4 from 2.4 to get -1.6.

$$-0.5x=-1.6$$

Divide both sides by -0.5.

$$x=\frac{-1.6}{-0.5}$$

Expand \frac{-1.6}{-0.5} by multiplying both numerator and the denominator by 10.

$$x=\frac{-16}{-5}$$

Fraction \frac{-16}{-5} can be simplified to \frac{16}{5} by removing the negative sign from both the numerator and the denominator.

$$x=\frac{16}{5}$$
