Question

solve x+y=16 and x-2y=-2 graphically​

Answer 1

Answer:

x-2y+2=0

x-2y=-2

x=-2+2y

put y =1

x=-2+2 (1)

x=-2+2

x=-0

put y=-2

x=-2+2 (-2)

x=-2-2

x=4

put y=3

x=-2+2 (3)

x= -2+6

x=4

Do same thing with another equation

then draw a graph

Answer 2

Step-by-step explanation:

1. x+y=16. given....
2. x-2y=-2

x + y = 16

x - 2y= -2

- + -

3y = 18

y=6. put in I eq.

x+y=16

x+6=16

x=16-6

x=10
