It does if x=2. That's the solution of your equation.
x = -3, y = 7
x=-2, y=2
x = 3 and y = 2
There is one solution for x and one solution for y. The solution is: x = -1 ; y = 2
It is (-1, 3).
It does if x=2. That's the solution of your equation.
The solution is: x = 1 and y = -1
y = x + 1
x = -3, y = 7
x=-2, y=2
Yes: x = -2
x=2
x=-2
There is no solution since the equation is inconsistent.
If x - 4y = 2 and x + 4y = 2 then the only solution is when y = 0 and thus x = 2.
x+1=x+2 x=1+2+x 0x=1+2 0x=3 0x=/=3 (=/= means does not equal) so there is no solution
