Question

For which system of equations is (2, 2) a solution?
A.
–3x + 3y = 0
x + 6y = 10
B.
–2x + 5y = –6
4x – 2y = 4
C.
5x – 2y = –6
3x – 4y = 2
D.
2x + 3y = 10
4x + 5y = 18
Please help

Answer 1

Plug 2 for x and 2 for y In the equations :)

Answer 2

ok Thanks! so do I multiply x times 2 and y times 2?

Answer 3

You place 2 for x and 2 for y :)

The answer would be the last one:
2x + 3y = 10 ---> Place 2 for x and 2 for y ---> 2(2) + 3(2) = 10 ---> 4 + 6 = 10 ---> TRUE
4x + 5y = 18 ---> Place 2 for x and 2 for y ----> 4(2) + 5(2) = 18 ---> 8 + 10 = 18 ---> TRUE

Answer 4

ohhhhh Now I get it Thankyou sooo much your a lifesaver!

Answer 5

No problem! Glad I helped!!!
