-3y + 10x = -5
3y - 6x=9

x=-1 y=1

Step-by-step explanation:

-3y+10x=-5

3y-6x=9

Add both equations together

-3y+3y+10x-6x=-5+9

0+4x=-4

4x=-4

Divide both sides by 4

4x/4=-4/4

x=-1

Substitute x=-1 in 3y-6x=9

3y-6(-1)=9

3y+6=9

3y=9-6

3y=3

Divide both sides by 3

3y/3=3/3

y=1

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%
