Simplify

4 x - 32 x

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

(4 - 32) x

Subtract the numbers

- 28 x

- 28 x - 4 = 0

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

- 28 x = 0 + 4

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

- 28 x = 4

Change the signs on both sides of the equation

28 x = - 4

Divide both sides

\frac{28 x}{28} = \frac{- 4}{28}

Divide the numbers

x = \frac{- 4}{28}

Solution

More Steps

Evaluate

\frac{- 4}{28}

Cancel out the common factor 4

\frac{- 1}{7}

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

- \frac{1}{7}

x = - \frac{1}{7}

Alternative Form

x = - 0. \dot{1} 4285 \dot{7}
