Question

(i) y=x+ 2
(ii) y=x-2
(ii) y=-x+ 2
(iv) x + 2y = 6​

Answer 1

Answer:

i dont understand

Step-by-step explanation:

what to do this

Answer 2

Answer:

1. y=x+2 => y-x= 2
2. y=x-2. => y-x= 2
3. y=-x+2=>x+y =2
4. x+2y=6

from equation 1 and 2

y-x= 2

y-x=-2

- + +

________

0 =4. (using elimination method)

from equation 3 and 4

y +x= 2

2y+x= 6

- - -.

_________

-y = -4

y = 4

now using value of y in equation 3

y +x =2

4+x=2

x=2-4

x=-2

x=-2 and y =4
