6x + 3y = 15, if x = 2:

6 (2) + 3y = 15 Plug 2 into x

12 + 3y = 15

-12 - 12 Subtract 12 for both side

3y = 3 Divide 3 for both side

y = 3

6x + 3y = 15, if x = 5:

6 (5) + 3y = 15 Plug 5 into x

30 + 3y = 15

-30 - 30 Subtract 30 for both side

3y = - 15

/3 / 3 Divide 3 for both side

y = - 5
