<h2>Linear equations</h2>
<em>The </em><em>graphical representation</em><em> of a linear equation is a straight line. To solve</em><em> linear equations</em><em>, i</em><em>t is important to keep in mind the following key concepts:</em>
- <em>Maintain the balance of the equation by applying the </em><em>same operations</em><em> to both sides of the equation.</em>
- <em>Clear the variable using like terms.</em>
- <em>Use </em><em>inverse operations</em><em> to rearrange the equation.</em>
<h3>-x + 5 = 1</h3>
We will subtract 5 from both sides.
<h3>−x + 5 - 5 = 1 - 5</h3><h3>−x = -4</h3>
<em>We divide both sides by -1.</em>
<h3>-x/x = -4/-1</h3><h3>x = 4</h3>
Answer: <em>Therefore the solution of the exercise </em><em>-x+5=1,</em><em> is </em><em>x = 4</em><em>. The </em><em>correct option</em><em> is </em><em>"D".</em> ✅

She returned the bottle of 250 milliliter in lithium stock where another 175 milliliter of lithium was already present in the stock.
Quantity of lithium before return = 175 milliliter.
Quantity of lithium that she returned = 250 milliliter.
Total stock would be now = 175 + 250 = 425 milliliter.
So, there was 425 milliliter of lithium before she used any of it.
Hence, 425 milliliter is the final answer.
Answer:
8 + 2x
Step-by-step explanation:
Given that :
Kyle's game time = x
Trent's game time = 4 hours more than Kylie = 4 + x
Megan's game time = 2 times more than Trent ; this equals ; 2 * (4 + x) = 2(4 + x) = 8 + 2x
