Question

what is the solution to the equation 5x -2y =-9
2,-4
1,-3
-1,2
-2,5

Answer 1

what do u think it is

Answer 2

easiest way to do this is to plug in your x and y values

Answer 3

Idk how to do this can u like explain it to me

Answer 4

yeah sure. it's actually like this when we have an equation what we have on the right side must equal what we have on the left.

Answer 5

ok but..how do we make it equal?

Answer 6

so, the correct answer will be the one where your answer gets you 9 when you plug in x and y

Answer 7

Oh ok

Answer 8

i got B

Answer 9

Please express your solutions as points: enclose each set of numbers inside parentheses:

2,-4
1,-3
-1,2
-2,5

becomes (2,-4), (1,-3), and so on.

Is (2,-4) a solution? This asks, "when x=2 and y=-4, is 5x -2y =-9 true or false?

Please rewrite 5x -2y =-9. Let x=2 and let y=-4. Is the resulting equation true?

Answer 10

@study_123 can you show us your work?

Answer 11

Note: You don't "make it equal."
Rather, you CHECK whether the equatino is true for a given point (x,y).

Answer 12

OK,
5*1-2*-3=-9

don't forget your ( )

5(1)-2(-3) = -9?

Answer 14

Yes

Answer 15

5(1) = 5

and 2(-3) = - 6

but we have

5-(-6) = 5+6 = 11

Answer 16

so you're saying my answer is wrong?

Answer 17

The answer is C.

Answer 18

are u sure

Answer 19

yes

Answer 20
