x = 3 and y = 2
70000000y=35t
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
y= -9
x = 3 and y = 0
(x, y) = (3, 7) is a solution.
x = 3 and y = 2
70000000y=35t
2x plus 3y
5y = 3y + 12 5y - 3y = (3y - 3y) + 12 2y = 12 y = 6
x - 3y = -3: multiply by -2 giving -2x + 6y = 6, but -2x + 6y = 12 so we have a problem! Misprint?
y= -9
(10,13)
x = 3 and y = 0
No.
-3y + z = 12
4x+3y = 12 3y = -4x+12 y = -4/3x+4
