Question

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

(x + 7)y = 10


A.
(13, 2)

B.
(2, 1)

C.
(3, 1)

D.
(4, 1)

Answer 1

i got b

Answer 2

let's see you mean x+7y = 10 ?

Answer 3

Answer 4

yeah the answer would be 2n1

Answer 5

should probably re-write this.

x+7y = 10

7y = 10-x

Answer 6

then you can see what points satisfy the equation. by plugging in x, and if you get the same value for y then the point satisfies the equation.

Answer 7

k

Answer 8

7(y) = 10-x

let's try this one

B (2,1)

SO when x = 2 y must be 1

7(y) = 10-2

y = 8

so that point doesn't work.

you must try again
