|2x - 1|  =  | - x - 2|

Thus ;

2x - 1 =  - x - 2

Add both sides x

2x + x - 1 =  - x + x - 2

3x - 1 =  - 2

Add both sides 1

3x - 1 + 1 =  - 2 + 1

3x =   - 1

Divide both sides by 3

\frac{3x}{3}  =  \frac{ - 1}{3}  \\

x =  -  \frac{1}{3}  \\

<h2>Or </h2>

2x - 1 =  - ( - x - 2)

2x - 1 = x + 2

Subtract both sides x

2x  - x  - 1 = x - x + 2

x - 1 = 2

Add both sides 1

x - 1 + 1 = 2 + 1

x = 3

There u go ...

Answer:

JML=142 degrees

Step-by-step explanation:

This shape is a rhombus, as all 4 sides are equal, but the angle measures are not. One of the properties of a rhombus is that opposite angles are congruent, and adjacent angles are supplementary. Only the second one is important. Since angles KLM and angle JML are supplementary, the equation KLM+JML=180 can be used. KLM is then substituted by the given angle measure, 38 degrees, to get an equation such as JML+38=180. Now, to solve for JML, 38 must be subtracted from both sides of the equation, which leaves teh answer of JML=142.
