Subtract the terms

More Steps

Simplify

3 x - 203 x

Collect like terms by calculating the sum or difference of their coefficients

(3 - 203) x

Subtract the numbers

- 200 x

- 200 x - 20 = 0

Move the constant to the right-hand side and change its sign

- 200 x = 0 + 20

Removing 0 doesn't change the value,so remove it from the expression

- 200 x = 20

Change the signs on both sides of the equation

200 x = - 20

Divide both sides

\frac{200 x}{200} = \frac{- 20}{200}

Divide the numbers

x = \frac{- 20}{200}

Solution

More Steps

Evaluate

\frac{- 20}{200}

Cancel out the common factor 20

\frac{- 1}{10}

Use \frac{- a}{b} = \frac{a}{- b} = - \frac{a}{b} to rewrite the fraction

- \frac{1}{10}

x = - \frac{1}{10}

Alternative Form

x = - 0.1
