Answer:
Solving equation i and ii, we get;
3x-3y+x+3y=9+12
4x=21
x=21/4
Putting the value of x in equation ii.
(21/4)+3y=12
3y=12-(21/4)
3y=(48-21/4)
y=27/(4*3)
y=9/4
The greatest common factor of both numbers is 6 so you would take out that 6 since both of those numbers can be multiplied by it. So, your answer would be 6(5x+1) and if you multiply that 6 back in, you will go back to the original equation.
