Hi my friend
I found it thank you.
by which theorem?
I don't know why don't show the letters...
1)3x+3y=10
2)(-9x - 9y)/-3 = -30/-3 <=> 3x + 3y = 10 so 1) = 2) so have solution for every x,y
Yes you are right There is no x and y!!!
x = - 1 - y and replace this in the other 3(- 1 - y)=4 - 3y <=> - 3 - 3y = 4 - 3y so -3 = 4 is false and we dont have solutions
13+3x=13+2x <=> 13-13=2x-3x <=> 0=-x <=> x=0/-1 <=> x=0
