Solve 0.21x+0.42=0.18x-3

$$0.21x+0.42=0.18x-3$$

Solve for x

$$x=-114$$

Steps for Solving Linear Equation

Subtract 0.18x from both sides.

$$0.21x+0.42-0.18x=-3$$

Combine 0.21x and -0.18x to get 0.03x.

$$0.03x+0.42=-3$$

Subtract 0.42 from both sides.

$$0.03x=-3-0.42$$

Subtract 0.42 from -3 to get -3.42.

$$0.03x=-3.42$$

Divide both sides by 0.03.

$$x=\frac{-3.42}{0.03}$$

Expand \frac{-3.42}{0.03} by multiplying both numerator and the denominator by 100.

$$x=\frac{-342}{3}$$

Divide -342 by 3 to get -114.

$$x=-114$$
