<span>x+2y=200
x=y+50 
if x + 2y = 200, then let's solve it for x... 
x = 200 - 2y (subtracted 2y from both sides) 
Now we have two "x +" equations" 
x = y + 50
x = 200 - 2y 
If x equals two things, those two things equal each other (transitive property) 
y + 50 = 200 - 2y 
3y + 50 = 200 (added 2y to both sides) 

3y = 150 (subtracted 50 from both sides) 
y = 50. 
if y = 50, sub 50 back in for y into either of the two original equations (how about both to check?) 
x + 2(50) = 200
x + 100 = 200
x = 100 
x = 50 + 50
x = 100 
it's the same, so x = 100, y = 50
The lines cross at (100, 50)
hopes this helps :) :D :)</span>
