Hello there! the answer would be x = 3/4.
You are given the two equations: 4x - 2y = 8 and y = 1/2x + 2. You are asked to solve via substitution. To do this, substitute the value of y in the second given equation into the first given equation, and solve using PEMDAS.
4x - 2(1/2x + 2) = 8 - Start by distributing 2 into (1/2x + 2).
4x - 1x + 4 = 8 - Combine like terms.
3x + 4 = 8 - Subtract 4 from both sides.
3x = 4 - divide both sides by 3.
x = 3/4. This is your final answer.
I hope this was helpful, have a great day! :)

Answer:
The answer is <u>D. quadrilaterals</u>
Step-by-step explanation:
- <u><em>All </em></u><u><em>trapezoids </em></u><u><em>are squares. If a shape is a square, then it is also a rectangle and a rhombus. A</em></u><u><em> trapezoid </em></u><u><em>is a </em></u><u><em>quadrilateral </em></u><u><em>with exactly one set of parallel sides</em></u>

<span>Equivalent fraction : </span>The fraction thus generated looks different but has the same value as the whole
<span>Common denominator : </span>The equivalent fraction and the other fraction involved in the calculation share the same denominator
<span>Step 3 :</span>Pulling out like terms :
<span> 3.1 </span> Pull out like factors :
<span> x2 + x</span> = x • (x + 1)
Adding fractions that have a common denominator :
<span> 3.2 </span> Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
