Evaluate

5 x - 20 x

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

(5 - 20) x

Subtract the numbers

- 15 x

- 15 x - 15

- 15 x - 15 + 10 = 0

Add the numbers

- 15 x - 5 = 0

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

- 15 x = 0 + 5

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

- 15 x = 5

Change the signs on both sides of the equation

15 x = - 5

Divide both sides

\frac{15 x}{15} = \frac{- 5}{15}

Divide the numbers

x = \frac{- 5}{15}

Solution

More Steps

Evaluate

\frac{- 5}{15}

Cancel out the common factor 5

\frac{- 1}{3}

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

- \frac{1}{3}

x = - \frac{1}{3}

Alternative Form

x = - 0. \dot{3}
