Answer:
The answer is below
Step-by-step explanation:
The question is not complete. But I would solve a similar question.
Solution:
A quadrilateral is a polygon shape with four sides and four angles.
Two polygons are said to be similar if they have the same shape and the ratio of their corresponding sides are equal to each other (that is their corresponding sides are in the same proportion).
Given that Quadrilateral ABCD is similar to quadrilateral GHIJ, hence their corresponding sides are similar.

Step-by-step explanation:
<u>Step 1: Define systems</u>
-5x - 3y = 12
y = x - 12
<u>Step 2: Solve for </u><em><u>x</u></em>
<em>Substitution</em>
- Substitute in <em>y</em>: -5x - 3(x - 12) = 12
- Distribute -3: -5x - 3x + 36 = 12
- Combine like terms: -8x + 36 = 12
- Isolate <em>x</em> term: -8x = -24
- Isolate <em>x</em>: x = 3
<u>Step 3: Solve for </u><em><u>y</u></em>
- Define original equation: y = x - 12
- Substitute in <em>x</em>: y = 3 - 12
- Subtract: y = -9
<u>Step 4: Graph systems</u>
<em>Check the solution set.</em>
