Question

Which ordered pair in the form (x, y) is a solution of this equation?
x + 7y= 10

Answer 1

Answer: (3, 1)

Explanation:

Plug in each coordinate and see if the equation holds true:

`(13, 2)\\13+2(7)=13+14=27\\eq 10`

`(2, 1)\\2+7(1)=2+7=9\\eq 10`

`(4, 1)\\4+7(1)=4+7=11\\eq 10`

`3+7(1)=3+7=10`
