Find an equivalent system of equations for the following system:
x + 2y = 2
- 4x + 4y = -8
x + 2y = 2
- 4x - 2y = 10
x + 2y = 2
5x + 4y = 8
x + 2y = 2
5x - 2y = 10
x + 2y = 2
5x – 2y = -8

Step-by-step explanation:

Given the system of equations

Subtract from the first equation the second equation:

Therefore, equivalent system is

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
