Solve by elimination method 1. X+2y/3 =-1 and x-y/3=3​

Answer»

Answer:

X=11 and y=2 is the correct answer

Step-by-step EXPLANATION:

x+2y/3=-1

X+2y=-3 is the first equation

and

x-y/3=3

x-y=9 is the SECOND equation

now,by SUBTRACTING eq. first from second equation

x-y=9

X+2y=-3

now we will change sign in the second equation

so, -3y=-6

and y=2

and, x-2=9

so,X=11 And y=2
