Question

x + y = 11
-x = -y - 9
A. (8, 3)
B. (9, 2)
C. (11, 0)
D. (10, 1)

Answer 1

Re-arrange the equation thus,

\(x + y=11 \\-x + y=-9\)

Can you make any sense of it now?

Answer 2

medals if you give me the right answer
and i already knew how to do that i need to get this answer right or else i will fail this class

Answer 3

Add equation one and two to eliminate \(x\), the result is pretty straightforward from there..

Answer 4

If you did your algebra correctly, you'll get

\(2y=2\)

Divide both sides by 2 and ...

\(y=1\)

Answer 5

so d?

Answer 6
