Answer:

x=0

Step-by-step explanation:

Assuming the two sides are equal length

2x+15 =x+15

Subtract 15 from each side

2x =x

Subtract x from each side

2x-x = x-x

x=0

Step-by-step explanation:

<em>Given</em><em>, </em>

<em>RSTU</em><em> </em><em>is</em><em> </em><em>a</em><em> </em><em>parallelogram</em><em>, </em>

<em>so</em><em>,</em><em> </em><em>we</em><em> </em><em>need</em><em> </em><em>to</em><em> </em><em>find</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>,</em>

<em>let's</em><em> </em><em>find it</em><em>, </em>

<em>2</em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>x</em><em>+</em><em>1</em><em>5</em><em> </em><em> </em><em> </em><em>(</em><em>opposite</em><em> </em><em>side of</em><em> </em><em>parallelogram</em><em> </em><em>are</em><em> </em><em>equal</em><em> </em><em>and</em><em> </em><em>parallel</em><em>)</em>

<em>2</em><em>x</em><em> </em><em>-</em><em> </em><em>x</em><em> </em><em>=</em><em> </em><em>1</em><em>5</em><em>-15</em>

<em>x</em><em>=</em><em>0</em>

<em>Therefore</em><em>, </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

<em>If</em><em> </em><em>you</em><em> </em><em>have</em><em> </em><em>doubt</em><em>.</em><em> </em><em>then</em><em> </em><em>let's</em><em> </em><em>clear</em><em> </em><em>it</em><em> </em><em>by</em><em> </em><em>putting</em><em> </em><em>the</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>2</em><em>×</em><em>0</em><em>+</em><em>1</em><em>5</em><em> </em><em>=</em><em> </em><em>0</em><em>+</em><em>1</em><em>5</em>

<em>1</em><em>5</em><em>=</em><em>1</em><em>5</em><em> </em><em>{</em><em>as</em><em> </em><em>already</em><em> </em><em>said</em><em> </em><em>that</em><em> </em><em>the</em><em> </em><em>sides</em><em> </em><em>are</em><em> </em><em>equal</em><em>}</em>

<em>proved</em><em>.</em><em>.</em>

<em>so</em><em>,</em><em> </em><em>the</em><em> </em><em>value of</em><em> </em><em>x</em><em> </em><em>is</em><em> </em><em>0</em><em>.</em>

<em><u>Hope</u></em><em><u> </u></em><em><u>it helps</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em><em><u>.</u></em>
