Answer 1

1)x-y-2=0 2x-3y+1=0

x=y+2

2(y+2)-3y+1=0

x=y+2

2y+4-3y+1=0

x=7

y=5

2) -x+y-4=0 4x+y+1=0

x=y-4

4(y-4)+y+1=0

x=4-y

4y-16+y+1=0

x=4-y 5y=15

X=1

y=3

3) 3x+y-4=0 5x+y-10=0

y=4-3x 5x+4-3x-10=0

y=4-3x

2x=6

y=-5 x=3

4) 8x-3y-7=0

3x+y-9=0

8x-3y-7=0 y=9-3x

8x-3(9-3x)-7=0

y=9-3x

8x-27+9x-7=0

y=9-3x

17x=34 y=9-3x

x=2

y=3

5)x+5y+2=0

0,5x-y-6=0

x=-5y-2

0,5(-5v-2)-v-6-ʊ

x=-5y-2

-2.5y-1-y-6-0

x=-5y-2 -3.5y=7

x=8

y=-2

6)12x-y-18=0 x+0,5y-5=0

y=12x-18

x+0,5(12x-18)-5=0

y=12x-18 x+6x-9-5=0

y=12x-18 7x=14

y=6 x=2
