Question

What is the solution of the system? Use elimination.
3x – 4y = 9
–3x + 2y = 9
A. (3, 9)
B. (–27, –9)
C. (–3, –6)
D. (–9, –9)
d?

Answer 1

-6y=9

Answer 2

If you add the 2 equations you will eliminate x

Answer 3

and that will give you -2y = 18
now ites easy to find value of y

Answer 4

9?

Answer 5

-9

Answer 6

NO
18 / -2 = ?

Answer 7

-9

Answer 8

right y = -9
Now p[lug this value of y into the first equation and solve for x

Answer 9

SO it b?

Answer 10

3x -4(-9) = 9
3x + 36 = 9

- find x

Answer 11

first subtract 36 from both sides of the equation
then dividing by 3 will give you value of x

Answer 12

so it is d

Answer 13

can you show me your work
