Question

write two solution for the equation x-2y=19​

Answer 1

x+ 2y=5

Put x=0

0+2y=5

2y=5

y=5/2

3.0

Now, put y=0

x+2(0)=5

x+0=5

x=5

Answer 2

Answer:

when x = 21 then y = 1   (21, 1)

when x = 23 then y = 2  (23, 2)

Step-by-step explanation:

x - 2y = 19

put y = 1

x - 2(1) = 19

x - 2 = 19

x = 19 + 2

x = 21

put y = 2

x - 2(2) = 19

x - 4 = 19

x = 19 + 4

x = 23
