Answer 1

The answer to your question is below

Explanation:

First system

2x - 2y = 12

-2x - 3y = -22

0 - 5y = -10

y = -10 / -5

y = 2

Solution (x , 2)

Second system

2x - 6y = 10

-2( x + 8y = 5)

2x - 6y = 10

-2x - 8y = -10

0 -14y = 0

y = 0 / -14

y = 0

2x - 6(0) = 10

2x = 10

x = 10/2

x = 5

Solution (5, y)

Third system

4(3x - y = - 5)

x + 4y = 7

12x - 4y = -20

x + 4y = 7

13x + 0y = -13

x = -13/13

x = -1

-1 -+ 4y = 7

4y = 7 + 1

4y = 8

y = 8/4

y = 2

Solution (x, 2)

Forth system

x - y = 2

2x + y = 13

3x = 15

x = 15/3

x = 5

Solution (5, y)
