Please answer all of these!! I need answers quick please! I'm in after school classes!! please!! ):
with the correct steps to!!

2x-y=1
2x+2y=10


2x+3y=8
5x-2y=1


3x+5y=7
4x+3y=2


5x-y=15
x+y=-3


3x-y=6
2x+5y=-13


3x+5y=1
x-y=-5


2x-5y=3
3x+2y=14


2x+3y=6
3x=2y=-1


3x-y=18
x+2y=-1


and just this word equation please!!

if Elizabeth and Asha put their money together they have $36. If Elizabeth's money was halved and Asha's money doubled they would have $42. How much money do each have?

1. x = -1, y = 3
2. x = 1, y = 2
3. x = -1, y = 2
4. x = 2, y = -5
5. x = 75/51, y = 25/17
6. x = 3, y= -2
7. x = -4, y = -1
8. x = 3, y = -4
9. x = -5, y = 3

1.
1.
2x -y = 1, ===> y = 2x-1 ......................... [1]
2x +2y = 10 ......................... [2]

From [1] and [2], 2x +2(2x-1) = 10
2x +4x -2 = 10, ===> 6x = 2+10 = 12

x = 12/6 = 2. >=======================< ANSWER
AND
y = 2*2-1 = 3 >====================< ANSWER
