Answer:
x = -4 ; y = 1
Step-by-step explanation:
2x + 6y = -2 --------(i)
-x + 2y = 6 --------(ii)
2x + 6y = -2
(ii)*2 -2x + 4y = 12
add; 10y = 10
y = 10/10
y = 1
Substitute y in (i)
2x + 6*1 = -2
2x +6= -2
2x = -2-6
2x = -8
x = -8/2
x = -4
Good evening ,
Answer:
Step-by-step explanation:
2x + 6y = -2 (1)
-x + 2y = 6 (2)
(1) - 3×(2) ⇒ (2x+6y) - 3×(-x+2y) = -2 - 3×6
⇒ 5x = -20
⇒ x = -4
therfore (1) ⇒ 4 + 2y = 6 ⇒ 2y = 2 ⇒ y=1.
