Answer:
Y= -4
Step-by-step explanation:
According to the rules of GEMDAS, division precedes subtraction.
Substitute 20 into where X is in the equation, so it would look like:
20/5-8=Y
From here, simplify. 20/5 is 4. 4-8=-4
Here's how work would look like on my paper"
X/5-8=Y
20/5-8=Y
4-8=Y
Y=-4
It's the last choice. In the top row you have the 1's that are the coefficients on the x and the y, and the solution for that equation is 21; in the second row you have the 5 from the x and the 4 from the y and the solution for that equation which is 20. I'm more used to writing them down instead of across, but there you have it anyways
