Question

2. 3x+2y=7
-3x+11=y

A.(6,-3)
B.(6.-7)
C.(-4,19/2)
D.(5.-4)

Answer 1

Add the equations together. That will eliminate x and you can solve for y easily.

Answer 2

so what am substitute the x for

Answer 3

am i*

Answer 4

3x + 2y = 7
-3x + 11= y Change bottom equation to: -3x - y = -11

Now rewrite the first equation and the new version of the second equation:

3x + 2y = 7
-3x - y = -11 Now add the equations together
y = -4

There is only one solution with y = -4, so it must be the correct choice.
