Question is attached. answer and provide work. worth 50+ points

NUMBER 1
Elimination of x to find y
2x + 3y = 1
2x +  y  = -9
- (substract)
       2y = 10
         y = 5

Elimination of y to find x
2x + 3y = 1   (multiply 1)
2x +  y  = -9  (multiply 3)

2x + 3y = 1
6x + 3y = -27
- (substract)
-4x        = 28
   x        = -7

NUMBER 2
Elimination of y to find x
10x - 2y = 24
 6x + 2y = 8
+ (add)
16x         = 32
   x          = 2

Elimination x to find y
10x - 2y = 24 (multiply 3)
 6x + 2y = 8   (multiply 5)

30x - 6y = 72
30x + 10y - 40
- (substract)
        -16y = 112
             y = -7

NUMBER 3
Eliminate y to find x
  x - 4y = 1
2x + 4y = 26
+ (add)
3x         = 27
  x         = 9

Eliminate x to find y
  x - 4y = 1    (multiply 2)
2x + 4y = 26 (multiply 1)

2x - 8y = 2
2x + 4y = 26
- (substract)
       -12y = -24
             y = 2

NUMBER 4
Elimination of y to find x
x + y = 6
x - y = 2
+ (add)
2x    = 8
  x    = 4

Elimination of x to find y
x + y = 6
x - y = 2
- (substract)
    2y = 4
      y = 2

NUMBER 5
Elimination of q to find p
  p - q = 8
2p - q = 19
- (substract)
-p       = -11
 p       = 11

Elimination of p to find q
  p - q = 8    (multiply 2)
2p - q = 19  (multiply 1)

2p - 2q = 16
2p -   q = 19
- (substract)
    -q = -3
     q = 3
