Question

For the first one, subtract x from both sides.

For the second one, subtract 9y from both sides.

anonymous · Answer

I am pretty sure there is a typo somewhere in the equations. Can you please recheck?

anonymous · Answer

Yes it did look a little strange..

anonymous · Answer

okay let me check that is the question that the teacher give me

Hint: Try to get both equations into this form first:
$$ax+by=c$$

anonymous · Answer

i think u should first get rid of the x in da first equation then ull juz solve for y then plug it in for da next equation nd solve for x

anonymous · Answer

x+2y=x+4
if then  
2y =4 and hence y=4/2=2

9y=-3x+9+9y
9y -9y=-3x+9+9y-9y
or 0=-3x+9
or 3x=9
or x=9/3=3
