What is the solution of each system of equations? Show your work-6x-5y=64x+y=3

Step-by-step explanation:

-6x-5y=64x+y=3

-6x-5y=64x+y

-6x-64x=y+5y

-70x=6y

divide by 2

-35x=3y

y=-(35/3)x

y+64x=3

-(35/3)x+64x=3

-35x+192x=9

157x=9

x=9/157

y=-35/3x

Step-by-step explanation:

First calculate the hypotenus using the pythagorian theorem

now let's calculate sin x° and cos y°

since x°+ y° = 90

sin x° = cos y°

so cos y° = 0.6
