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

(x-1)^2 - x(x-3) = 2y+3

Answer 1

x+y/2 - x-y/3 = 3/2     /*6  

(x-1)² - x(x-3) = 2y+3     

 

3(x+y) - 2(x-y) = 9

x² - 2x + 1 - x² + 3x = 2y + 3

 

3x + 3y – 2x + 2y = 9

x – 2y = 3 -1

 

x + 5y = 9

x – 2y = 2  /*(-1)

 

x+5y = 9

-x + 2y = -2

-----------------

7y = 7  /:7

y = 1

 

x + 5*1 = 9

x = 9-5

x = 4

 

x = 4

y = 1
