Mathematics: Solve the system by elimination. x+ 5y = -1 5x + 15y = 5 The solution is ( , )

Step-by-step explanation:Please find the attachment. We have been given that in right triangle LMN, L and M are complementary angles and . We are asked to find the .We know that sine relates opposite side of right triangle to hypotenuse. We also know that cosine relates adjacent side of right triangle to hypotenuse. We can see from the attachment that LM is hypotenuse and MN is adjacent side of our given triangle.Therefore, is as well....

x=4, y=-1. (4, -1).

Step-by-step explanation:

x+5y=-1

5x+15y=5

-5(x+5y)=-5(-1)

5x+15y=5

-5x-25y=5

5x+15y=5

-10y=10

y=10/-10

y=-1

x+5(-1)=-1

x-5=-1

x=-1+5

x=4
