Solve the system of equations by elimination.
4x - 5y = 11 and -4x + y = 1
What is the solution?

x = - 1

y = -3

Step-by-step explanation:

4x - 5y = 11

-4x + y = 1        +

-4y = 12

y = -3

Now, plug y = -3 back into any equation

-4x - 3 = 1

-4x = 4

x = - 1

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)
