Answer: 4x − 2y = 6 . . . . . (1)
2x + y = 5 . . . . . (2)
(2) x 2 => 4x + 2y = 10 . . . . . (3)
(1) - (3) gives: -4y = -4
y = -4/-4 = 1
From (2), 2x + 1 = 5 => 2x = 5 -1 = 4
x = 4/2 = 2
Solution is (2, 1)
Substituting the solution into the options gives that
−4x − 2y = 10
−4y = 4 −4x
has the same solution.
hope this helped!! :)
