Answer 1

Step-by-step explanation:

hope you understand this Sofia.

Answer 2

Step-by-step explanation:

2x+y=22 ...(1)

x+2y=29 ....(2)

Multiplying equ (2) by 2 we get,

2x+4y= 58 ...(3)

Subtracting equ (2) & equ (1)

2x+4y=58

- 2x+y = 22

3y= 36

y= 36

3

y= 12

Substituting the value of y=12 in equ (1) we get,

2x+y=22

2x+12=22

2x=22-12

2x=10

x = 10

2

x= 5

(x,y) = (5,12)
