5x + 10y=35
2x + 12y=30

1. 5x+10y=35 x= 5 y= 1

2. 2x+12y=30 x= 3 y= 2

Step-by-step explanation:

1. 5x+10y

10+5=15; 15-10=5; x=5

10/5=2; 2/2=1; y=1

5(5)=25

10(1)= 10

25+10= 35

YAY!

2. 2x+12y

12/2=6; 6/2=3; x=3

12/6=2; y=2

2(3)=6

12(2)=24

24+6= 30

YAY!

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
