Hi!
If we multiply the top equation by (-2), then we can cancel out the y's.
-2(2x + 5y = 15)
-4x - 10y = -30
Now we add the second equation and our new equation together, and get:
x = 5
Now, we plug this in to one of the other equations
2(5) + 5y = 15
distribute
10 + 5y = 15
subtract 10 from both sides
5y = 5
divide both sides by 5
y = 1
Therefore, your answer is (5, 1)
Have a great day! :D
Answer:
(5, 1).
Step-by-step explanation:
2x+5y=15
5x+10y=35
Multiply the first equation by -2:
-4x - 10y = -30
Add this 2 second equation:
x = 5.
Plug x = 5 into the first equation:
10 + 5y = 15
5y = 5
y = 1.
