Answer:
x = -3
y = 3
Step-by-step explanation:
<u>Step 1</u>
X = 15 - 6y
<u>Step 2</u>
Replace x with 15 -6y in the second eqation
3(15 - 6y) + 4y = 3
45 - 18y + 4y = 3
45 - 3 = 18y - 4y
42 = 14 y
y= 3
find x:
X = 15 - 6(3)
x = -3

Molly shot 5 baskets per minute.
20/4=5
Nico shot 7 baskets per minute.
42/6=7
If said number is x, that means that twice (2 times) a number and 2x-7=13. Adding 7 to both sides, we get 2x=20 and by dividing both sides by 2 we get x=10. For 2, we see that the sum of a number and 6 is first priority, so we have (x+6)*7=-43. Dividing both sides by 7, we get x+6=-43/7. After that, we subtract both sides by 6 to get -43/7-6=x
