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)

(one way is to subsitute since both equal 9 you do 3x-4y=-3x+2y then add 3x to both sides 6x-4y=2y add 4y to both sides 6x=6y divide by 6 x=y now subsitute 3x-4x=9 -x=9 multiply -1  x=9  x=y y=-9)

use elimination
add them together to cancel x terms
3x-4y=9
-3x+2y=9  +
0x-2y=18
-2y=18
divide by 2
-y=9
multiply -1
y=-9
subsituete

3x-4y=9
3x-(4 times -9)=9
3x-(-36)=9
3x+36=9
subtract 36 from both sides
3x=-27
divide both sides by 3
x=-9

x=-9
y=-9

the answer is  in (x,y) form
(-9,-9)
the answer is none of them (D is closest)

Ihonestly don’t no that
