ok,

Answer 5

No solutions becuz you have two variables that are still in there, you cant solve it without knowing the value of the adverb, the best u could do is simplify.

:D

Answer 18

im srry, idk this

Answer 19

texaschic? can you help me lol

Answer 20

x + 3y = 9 --> x = -3y + 9
now sub -3y + 9 in for x in the other equation
3x - 3y = -13
3(-3y + 9) - 3y = -13
-9y + 27 - 3y = -13
-9y - 3y = -13 - 27
-12y = -40
y = 40/12
y = 10/3
now sub 10/3 in for y
x + 3y = 9
x + 3(10/3) = 9
x + 10 = 9
x = 9 - 10
x = -1
answer is (-1,10/3)
