2y = x + 3
aksik [14]

Answer:

Solution:  { -29/3 , -10/3 }

Step-by-step explanation:

2y = x + 3  ---------> equ 1

5y = x - 7    equ 2

equ 1 - equ s  ====>     -3y = 10

                                         y =  -10/3

Put y = -10/3 in equ 1

        2 * (-10/3)   = x + 3

         -20/3         = x + 3

          (-20/3) - 3   = x

        (-20/3) - (9/3)  = x

         (-20 - 9) / 3    =x

                x = -29/3

Solution:  { -29/3 , -10/3 }
