Solve for x |6-4x|=1

$| 6 - 4 x | = 1$

Step 1

Remove the absolute value term. This creates a $\pm$ on the right side of the equation because $| x | = \pm x$ .

$6 - 4 x = \pm 1$

Step 2

The complete solution is the result of both the positive and negative portions of the solution.

First, use the positive value of the $\pm$ to find the first solution.

$6 - 4 x = 1$

Move all terms not containing $x$ to the right side of the equation.

Subtract $6$ from both sides of the equation.

$- 4 x = 1 - 6$

Subtract $6$ from $1$ .

$- 4 x = - 5$

Divide each term in $- 4 x = - 5$ by $- 4$ and simplify.

Divide each term in $- 4 x = - 5$ by $- 4$ .

$\frac{- 4 x}{- 4} = \frac{- 5}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 x}{- 4} = \frac{- 5}{- 4}$

Divide $x$ by $1$ .

$x = \frac{- 5}{- 4}$

Simplify the right side.

Dividing two negative values results in a positive value.

$x = \frac{5}{4}$

Next, use the negative value of the $\pm$ to find the second solution.

$6 - 4 x = - 1$

Move all terms not containing $x$ to the right side of the equation.

Subtract $6$ from both sides of the equation.

$- 4 x = - 1 - 6$

Subtract $6$ from $- 1$ .

$- 4 x = - 7$

Divide each term in $- 4 x = - 7$ by $- 4$ and simplify.

Divide each term in $- 4 x = - 7$ by $- 4$ .

$\frac{- 4 x}{- 4} = \frac{- 7}{- 4}$

Simplify the left side.

Cancel the common factor of $- 4$ .

Cancel the common factor.

$\frac{- 4 x}{- 4} = \frac{- 7}{- 4}$

Divide $x$ by $1$ .

$x = \frac{- 7}{- 4}$

Simplify the right side.

Dividing two negative values results in a positive value.

$x = \frac{7}{4}$

The complete solution is the result of both the positive and negative portions of the solution.

$x = \frac{5}{4}, \frac{7}{4}$

Step 3

The result can be shown in multiple forms.

Exact Form:

$x = \frac{5}{4}, \frac{7}{4}$

Decimal Form:

$x = 1.25, 1.75$

Mixed Number Form:

$x = 1 \frac{1}{4}, 1 \frac{3}{4}$
