Question

Zad1 {y+2-(3-x)=0
{x-2=5-(2-y)
zad2 {3(x-y)+4x=8
{3(x-5y)=5-9y

Answer 1

1. 2.
{y+2-(3-x)=0 {3(x-y)+4x=8
{x-2=5-(2-y) {3(x-5y)=5-9y
{y+2-3+x=0 {3x-3y+4x=8
{x-2=5-2+y {3x-15y=5-9y
{y-1+x=0 {x-3y=8
{x=5+y {3x=5+6y
{y-1+(5+y)=0 {x=8+3y
{x=5+y {3(8+3y)=5+6y
{y+4+y=0 {x=8+3y
{x=5+y {24+9y=5+6y
{2y=-4 {x=8+3y
{x=5+y {24+3y=5
{y=-2 {x=8+3y
{x=5+(-2) {3y=-19
x=3 {y=8 i 1/3
y=-2 {x=8+ 8 i 1/3 x 3
x= 33
y=8 i 1/3
jakoś tak ;)
