More Steps

Simplify

2 x - 12 x

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

(2 - 12) x

Subtract the numbers

- 10 x

- 10 x - 34 = 0

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

- 10 x = 0 + 34

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

- 10 x = 34

Change the signs on both sides of the equation

10 x = - 34

Divide both sides

\frac{10 x}{10} = \frac{- 34}{10}

Divide the numbers

x = \frac{- 34}{10}

Solution

More Steps

Evaluate

\frac{- 34}{10}

Cancel out the common factor 2

\frac{- 17}{5}

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

- \frac{17}{5}

x = - \frac{17}{5}

Alternative Form

x = - 3.4
