​

Answer 1

Step-by-step explanation:

Answer is given above in the figure

Answer 2

Answer:

x= 47, y=74

Step-by-step explanation:

3x – 2y = -7

2y = 3x + 7

y = (3x + 7)/2

5x - 3y = 13

Substituting the value of y in the above equation, we get:

5x - 3(3x + 7)/2 = 13

10x - 9x - 21= 26

x = 26 + 21

x  = 47

Now to find y,

y = (3*47 + 7)/2

  = (141 + 7)/2

  = 148/2

y = 74
