Anarel [89]

Answer:

x=-2.2 y=-1.6

Step-by-step explanation:

8x+y=-16

-3x+y=5

5x=-11

x=-11/5 or -2.2

-3x+y=5

-3(-2.2)+y=5

6.6+y=5

-6.6+y=-6.6

y=-1.6

Please help<br> if x = 3 and y=-4 find x2 + y2 and x2 -y2

lions [1.4K]

1. Plug in the 3 in all the x’s that are in the equation:

(3)2 + y2 = for x2 + y2

(3)2 - y2 = for x2 - y2

This would get you for both equations..

6 + y2 = for x2 + y2

6 - y2 = for x2 - y2

2. Now let’s plug in the value of y which is -4:

6 + (-4)2 = for x2 + y2

6 - (-4)2 = for x2 + y2

This would get you for both equations...

-2 = x2 + y2

14 = x2 - y2

Hope this helped, have an awesome day!

WILL GIVE BRAINLIEST TO 1ST<br> 4x+188=6x+216

Ulleksa [173]

Answer:

x = -14

Step-by-step explanation:

Let's solve your equation step-by-step.

4x + 188 = 6x +216

Subtract 6x from both sides:

4x + 188 - 6x = 6x + 216 - 6x

-2x + 188 = 216

Subtract 188 from both sides:

-2x + 188 - 188 = 216 - 188

-2x = 28

Divide both sides by two:

$\frac{-2x}{-2}=\frac{28}{-2}$

$x = -14$
