Write as an ordered pair. 4x+2y=16 and -4y+x=4

(4,0)

Step-by-step explanation:

4x+2y=16

-4y+x=4

Multiply the first equation by 2

2(4x+2y)=16*2

8x +4y = 32

Add the 2nd equation

8x +4y = 32

x  -4y     =4

9x            =36

Divide each side by 9

9x/9 = 36/9

x=4

Now solve for y

-4y +x =4

-4y +4 = 4

Subtract 4 from each side

-4y +4-4=4-4

-4y =0

Divide by -4

-4y/-4 =0/-4

y=0

(4,0)

(4,0)

Step-by-step explanation:

4x + 2y = 16

2x + y = 8

y = 8 - 2x

-4y + x = 4

-4(8 - 2x) + x = 4

-32 + 8x + x = 4

9x = 36

x = 4

y = 8 - 2(4) = 0

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
