pls give me thanks and brainliest
<span>The y variable has the same coefficient so use elimination (subtract equations).
-2x = 8 - 6y
-(-15x = 21 - 6y)
------------------------
13x = -13 + 0
x = -1
Use this to find y in either equation. </span>
<span>-2(-1) = 8 - 6y
2 = 8 - 6y
2 - 8 = -6y
-6 = -6y
y = 1
(x,y) = (-1, 1)

Answer:
40 problems in 100 minutes
Step-by-step explanation:
This is a ratio problem.
You first divide 30 minutes by three to get how many problems she can do in 10 minutes. What you do to one side you do to the other side. So then, you should have 4 problems in 10 minute. Then, you multiply 10 by 10 and 4 by 10 to get 40 problems in 100 minutes.
