Subtract the terms

More Steps

Simplify

3 x - 23 x

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

(3 - 23) x

Subtract the numbers

- 20 x

- 20 x - 5 = 0

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

- 20 x = 0 + 5

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

- 20 x = 5

Change the signs on both sides of the equation

20 x = - 5

Divide both sides

\frac{20 x}{20} = \frac{- 5}{20}

Divide the numbers

x = \frac{- 5}{20}

Solution

More Steps

Evaluate

\frac{- 5}{20}

Cancel out the common factor 5

\frac{- 1}{4}

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

- \frac{1}{4}

x = - \frac{1}{4}

Alternative Form

x = - 0.25
