Question

x-y=3andx/3+y/2=6 then..................

Answer 1

Answer:

x-y=3

2x+3y=36

solve two equations

2x-3y=6

2x+3y=36

So x=21/2 and y=5

Answer 2

Step-by-step explanation:

x-y=3

x=3+y ........(1)

x/3+y/2=6

2x+3y/6=6

2x+3y=36

put (1) here,

2(3+y)+3y=36

6+2y+3y=36

6+5y=36

5y=30

y=6

put y=6 in (1)

x=3+6

x=9
