Answer:

<h2>14+3=17</h2><h3>or</h3><h2>(2*<u>7</u>) +3=17</h2><h3>basically 17=17</h3><h3 /><h3 />

Step-by-step explanation:

2x+3=17 and x =7

<h2>Let's Substitute:</h2><h3>(Because the variable is x and we have a value for it which is 7)</h3><h3>(<u>Bold and underlined is where the variable is in the equation)</u></h3><h3><u></u></h3>

Since x is equal to 7 we are going to substitute it in the equation.

<h3>So: </h3>
  1. (2*<u>7</u>) +3=17
<h2>14+3=17</h2><h2></h2>

I think this is the answer since already having the value of x is an answer please let me know if I am wrong or answered incorrectly so I can change my answer or let everyone know its wrong so it can be deleted. I only want to spread truthful information and assistance so let me know how I did by rating the answer, saying thanks or reporting it so I can improve.

Everyone Can Learn and will never stop learning!

<h3>Thank you! Hope this helps! </h3>
