Answer 1

2y=x
x-0,5=0

2y=x
x=0,5

2y=0,5
x=0,5

y=0,25
x=0,5

Answer 2

Jesli to jest układ równań to bedzie tak

{2y=x
{x-0,5=0

x=2y
2y=0,5 /:2

x=2y
y=0,25

x=2*025
y=0,25

x=0,5
y=0,25

Answer 3

{2y=x 0,5 to rowniez 1/2
{x-0,5=0
{2y = x
{2y - 1/2 = 0
{2y = x
{2y = 1/2 /:2
(2y =x
{y = 1/4 1/4 to 0,25 jak cos ;p
(2y =x
{y = 1/4
{2*1/4 = x
{y = 1/4
{1/2 = x
{y = 1/4
