Since when you multiply the numbers through, you see that the values are the same. Because of this, you can tell that you are demonstrating the distributive property.
Answer = C
First multiply -1 on the top to cancel X
It will give u:
-X+Y=-5
X-2Y=3 which gives u
y=2
Now, plug in the y (one of the equation it doesn’t matter which one) to solve for X
X-2=5
X=7
:(( I’m not sure on this one I’m sorry
The answer would be 5.79
Hope I helped :)
