Answer:

(-4,5)

Explanation:

use elimination method to solve

x+2y=6

3x+4y=32

make the x coefficient to be equal by multiplying the x by 3

3x+6y=18

-3x+4y=32

since the signs for the z coefficient are different than you add 3x+-3x=0

6y+4y=10y

18+32=50

10y=50

y=5

if y is equal to 5 then substitute

x+(2*5)=6

x+10=6

x=-4

(-4,5)
