1) x=2.8

2) x=1

Step-By-Step:

Q1) <em>2x + 2 - (2x - 14) = 5x + 2 </em>

<em>Simply</em><em> </em><em>the</em><em> </em><em>expression</em><em> </em>

<em>2x</em><em>+</em><em>2-2x</em><em>+</em><em>14</em><em>=</em><em>5x</em><em>+</em><em>2</em>

<em>collect</em><em> </em><em>like</em><em> </em><em>terms</em><em> </em>

<em>(</em><em>2x-2x</em><em>)</em><em> </em><em>+</em><em> </em><em>(</em><em>2</em><em>+</em><em>14</em><em>)</em><em> </em><em>=</em><em> </em><em>5x</em><em>+</em><em>2</em>

<em>simplify</em>

<em>16= 5x+2</em>

<em>swap</em><em> </em><em>sides</em><em> </em>

<em>5x</em><em>+</em><em>2</em><em>=</em><em>16</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em>-2</em><em> </em><em> </em><em> </em><em>-2</em>

<em>5x</em><em>=</em><em>16-2</em>

<em>5x</em><em>=</em><em>14</em><em> </em>

<em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>on</em><em> </em><em>its</em><em> </em><em>own</em><em> </em><em>we</em><em> </em><em>divide</em><em> </em><em>each</em><em> </em><em>side</em><em> </em><em>by</em><em> </em><em>5</em><em> </em><em>so</em>

<em>5x</em><em>=</em><em>14</em>

<em>÷</em><em>5</em><em> </em><em> </em><em>÷</em><em>5</em>

<u><em>x</em><em>=</em><em> </em><em>2</em><em>.</em><em>8</em></u><em> </em>

Q2) <em>2x + 10 - (-2x + 7) = -7x + 14 </em>

<em>Simply</em><em> </em><em>the</em><em> </em><em>expression</em><em> </em>

<em>2x</em><em>+</em><em>10</em><em>+</em><em>2x-7</em><em>=</em><em> </em><em>-7</em><em>+</em><em>14</em>

<em>collect</em><em> </em><em>like</em><em> </em><em>terms</em>

<em>(2x+</em><em>2x</em><em>)</em><em>+</em><em>(</em><em>10-7</em><em>)</em><em>=</em><em> </em><em>-7</em><em>+</em><em>14</em>

<em>simplify</em><em> </em>

<em>4x</em><em>+</em><em>3</em><em>=</em><em>7</em><em> </em>

<em> </em><em> </em><em> </em><em> </em><em>-3</em><em> </em><em>-3</em>

<em>4x</em><em>+</em><em>3-3</em><em>=</em><em>7-3</em>

<em>simplify</em><em> </em>

<em>4x</em><em>=</em><em>7-3</em>

<em>4x</em><em>=</em><em>4</em><em> </em>

<em>to</em><em> </em><em>get</em><em> </em><em>x</em><em> </em><em>on</em><em> </em><em>its</em><em> </em><em>own</em><em> </em><em>divide</em><em> </em><em>each</em><em> </em><em>side</em><em> </em><em>by</em><em> </em><em>4</em><em> </em><em>so</em><em>.</em><em>.</em><em>.</em>

<em>4x</em><em>=</em><em>4</em>

<em> </em><em>÷</em><em>4</em><em> </em><em>÷</em><em>4</em>

<em>x</em><em>=</em><em>1</em>

Solve for x in the diagram below
MrRissso [65]

Answer:

x=20 degrees

Step-by-step explanation:

because this is a supplementary angle, you add everything and set it equal to 180 degrees. so it would be x + 100 + 3x = 180. combine like terms to get 100 + 4x = 180. subtract 100 from both sides to get 4x = 80. divide by 4 on both sides to isolate the x and your final answer is 20. hope this helped! good luck in school xoxo
