Standard form is ax+by=c.

First, you should distribute to get rid of all parenthesis and grouping symbols.

13) y-5=-3(x+2)

y-5= -3x-6

Now, we want to move all variables to one side.

y-5= -3x=6

+3x +3x

y+3x-5=6

Now, move the constants to the other side.

y+3x-5=6

+5 +5

y+3x=11

Finally, rearrange to put x before y.

3x+y=11

Do this for the rest of the problems. I'll solve them without the words, but refer to the above example if you get lost.

14) y+1=4/5(x-5)

y+1=4/5x-4

y-4/5x+1= -4

y-4/5x= -5

-4/5x+y= -5

15) 0=x-4

x-4=0

x=4

(nothing much to do here because of the lack of variables)

16) y-3 = -1/2(x+4)

y-3= -1/2x-2

y+1/2x-3 = -2

y + 1/2x = 1

1/2x+y=1

17) y-4=1/3(x+3)

y-4=1/3x+1

y-1/3x-4=1

y-1/3x=5

-1/3x+y=5

18) y+5=3(x+3)

y+5=3x+9

y-3x+5=9

y-3x=4

-3x+y=4

hope this helps! please comment if you have any questions, and i'll answer to the best of my abilities
