2x + 2y = 6 . . . . . (1)
x + 3y = -1 . . . . . (2)
(1) x 3 => 6x + 6y = 18 . . . . . (3)
(2) x 2 => 2x + 6y = -2 . . . . . (4)
(3) - (4) => 4x = 20
x = 20/4 = 5
Answer:
Yes it is parellell
Step-by-step explanation:
Answer:
None (no solutions)
Step-by-step explanation:
-10q=-10q-7 (add 10q to both sides to get the costant 7 by itself)
-10q+10q=-10q+10q-7
0=-7 ( zero will never equal -7 hence there are no solutions to this equation)
