Question

What is the solution of the system? Use elimination. 3x – 4y = 9 –3x + 2y = 9

Answer 1

y=-9/2 => x= -9/3 = -3

Answer 2

Are these two equations?
3x-4y=9
-3x + 2y = 9

Answer 3

A. (3, 9)
B. (–27, –9)
C. (–3, –6)
D. (–9, –9)

Answer 4

IF so, I will add them to eliminate the x
-2y=18
y=-9
Can you take it from there and solve for x?

Answer 5

No dialog..........substitute the -9 for y in the 3x-4y=9
3x+36=9
3x=9-36=-27
x=-9
(-9,-9) Did you follow with understanding?
