Question

-x + 3y = 18
-6x – 3y = 3
help me plx

Answer 1

add both the equations vertically so that \(y\) stuff cancels out

Answer 2

-x + 3y = 18
-6x – 3y = 3
-------------------

Answer 3

add them, wat do u get ?

Answer 4

what do u mean

Answer 5

Add downward. The -x +-6x, the 3y+ the -3y and the 18 +3
this will give you a new equation.

Answer 6

?x+?y=?

Answer 7

I'll give you a hint.\[-7x+?y=?\]

Answer 8

i need 2 answers

Answer 9

-x + 3y = 18
-6x – 3y = 3
-------------------
-7x + 0 = 21

-7x = 21

x = -3

Answer 10

you got one answer, x = -3

Answer 11

simply substitute x = -3 in first equation, and solve for y

Answer 12

i still dont get it

Answer 13

-6x-3y=3

Answer 14

-6x-3y=3

Answer 15

we got x = -3

simply put this value in first equation, and solve for y

-x + 3y = 18
-(-3) + 3y = 18
3 + 3y = 18
3y = 15
y = 5

Answer 16

so the solution to given system is : x = -3, y = 5

Answer 17

see if that makes some sense :)

Answer 18

thank you
