Can anyone help me I was self isolating when my class was taught this and I can't get in contact with my teacher

Step-by-step explanation:

3x +2y = 13   (i)

x + 2y = 7    (ii)

Multiply the equation (ii) by (-1) and then add.

(i)              3x + 2y = 13

(ii)*(-1)      -x    - 2y = -7        {Now, add and y will be eliminated}

                 2x       = 6

                        x = 6/2

x = 3

Plug in x = 3 in equation (i)

3*3 + 2y = 13

  9 + 2y = 13

         2y= 13 - 9

         2y = 4

           y = 4/2

y = 2

i will u if u answer my question in math
