Question

Is (1, 1) a solution to this system of equations?
14x + y = 15
2x + 9y = 11

Answer 1

Well for these try plugging the x and y coordinates into the equation:

(1,1) where the first 1, is the x. And the second 1, is the y.

Answer 2

So it'd look something like 14(1)+1=15 and 2(1)+9(1)=15.
And if those are true, then yes, it would be a solution

Answer 3

So @karlieeeeeee, can you evaluate those equations for me and tell me if they're equal?

Answer 4

Ok so (1,1) look at it and try it out first

So set up he first problem like this

14(1) + (1) = 15

All you do is plug that in and you get your answer so like

14 x 1 + 1 x 1 = 15

First do (14 x 1)

So it’s 14 + 1 x 1 = 15

And 1x 1 is jus 1 so then add across

14 + 1 = 15

So the first one is correct so do the same with the second one and you’ll get your answer
