Question

Use substitution to determine if the given ordered pair is an element of the solution set for the system of equations. (-2, 2)

5y - 5x = 10
3x + 10 = 2y

Solution
Not a solution

Answer 1

as the problem says, substitute x and y and see if the equation works

Answer 2

i did i got for the 1st one, 10+10=10
and the 2nd .. -6+10=4
soo, is that not a solution?

Answer 3

do both answers have to be the same to be solution?

Answer 4

1st is 5(2)-5(-2)=10

Answer 5

both equations do not have to be the same, they just both have to be true

Answer 6

not a solution because the ordered pair does not work for both equations

Answer 7

See thats what i thought

Answer 8

@acxbox22 would you care to at least demonstrate that assessment?

Answer 9

So its a solution?

Answer 10

it's a solution if the x and y values make both equations true, you substitute the values and see if that's the case

Answer 11

Yal all have me confused lol, i thought it was not a solution

Answer 12

5(2)-5(-2)=10 calculate this

Answer 13

its 10+10=10

Answer 14

10+10 is equal to 20 not 10
so this doesnt work

Answer 15

(-2,2) would be a solution only if it worked for both equations, you already know this is not true
