2x plus 3y
The solution is: x = 1 and y = -1
5 - 2x = 8 x = -1 and 1/2 4x = 6 x = 6/4 or 3/2
Not sure what you mean; that equation certainly has a solution.

2x + 5y = 16 -2x - 3y = -14 2y = 2 y = 1 / x = 5.5 (5.5,1) or (5 1/2,1)
The solution is 1/2 or 0.5. This is how: 2x+1=7-10x 2x=6-10x 12x=6 x=1/2
4+2x-2x+1=13+6 Combine like terms. (4+1=5; 2x-2x=0; 13+6=19) 5=19 This problem has no solution.
x=1
x = 0
-2x plus 3y equals 1
The solution is (x, y, z) = (2.5, 1, 2.5).
