Question

6x-3y=-9;x-y=-6

Answer 1

You prefer substitution or elimination? :)

Answer 2

6x-3y=-9..........eq#1
x-y=-6...........eq#2
taking eq#2 and separate the y
y=x+6........eq#3
put eq#3 into eq#1
6x-3(x+6)=-9
6x-3x-18=-9
3x =-9+18
x=9\3
x=3
put the value of x into eq#3
y=3+6
y=9
so, the Solution set is { ( 3,9) }
this is the answer

Answer 3
