I need help with easy math

x = -1 and y = 9

The two equations are:

-9x + 2y = 23

-4x -y = -3

Now find for x in the first equation...

-9x + 2y = 23

-9x = 23 - 2y

x = (23 - 2y)/-9

Now place this value of x in the second equation and find for y...

-4{(23-2y)/-9} - y = -3

-92 + 8y + 9y = -3 * -9

17y = 27 + 92

y = 119/17

y = 7

Now place the value of y in the first equation," -9x + 2y = 23 " and find x

-9x + 2*7 = 23

-9x + 14 = 23

-9x = 23-14

x = 9/-9

x = -1

There you go! Hope it helps

i shoot u >:(

with love tho-

the answer is b

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.

solving with completing the square
