Use the elimination method to solve this system. − 4 x − 2 y = − 12, 4 x + 8 y = − 24

x = 6; y = -6

Step-by-step explanation:

-4x - 2y = -12

4x + 8y = -24

Add the two equations, so x is eliminated:

6y = -36

6y/6 = -36/6

y = -6

Plug in y, to solve for x

-4x - 2y = -12

-4x - 2(-6) = -12

-4x +12 = -12

-4x = -12 -12

-4x = -24

-4x/-4 = -24/-4

x = 6

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

the answer is 8.64
