8 because 12-4=8. Im writing this part for the 20 characters
Answer:
x=3, y=9
Step-by-step explanation:
5x-2y=-3
4x-2y=-6
Then:
solve for y:
-2y=-6-4x
y=3+2x
Substitute y into either equation:
4x-2(3+2x)=-6
4x-6-4x=-6
-6=-6, use other equation
5x-2(3+2x)=-3
5x-6-4x=-3
x-6=-3
x=3
then:
y=3+2(3)
y=9
I believe the answer is 2, the 3 large circles are filled with 5 dots each, the total number of dots is 17. 15 is the number closest to 17 that can be divided by 3 therefore there would be 2 left over (the 2 dots on the outside)
You would times it by -5
20/-4 = -5
-100/20 = -5
