Answer:
x = 6 and y = - 6
Step-by-step explanation:
- 4 x - 2 y = -12.......equ No 1
4 x + 8y = - 24.......equ No 2
Adding equ No 1 and equ No 2
6 y = - 36
∴ y = - 6
substitute y = - 6 in equ No 2
4 x + 8 y = -24
4 x + 8 ×( -6) = - 24
4 x - 48 = -24
4 x = -24 + 48
4 x = 24
∴ x = 6
x = 6 and y = - 6
-x + 2y = 6
6y = x + 18
Let's rewrite these equations.
-x + 2y = 6
6y - x = 18
If we multiply the second equation by -1 we can add both of them.
-x + 2y = 6
-6y + x = -18
Add:
-x + (-6y) + 2y + x = 6 + (-18)
2y - 6y + x - x = 6 - 18
-4y = -12
y = -12/-4
y = 3
Substitute y in the equation:
-x + 2y = 6
-x + 2.3 = 6
-x + 6 = 6
-x = 6 - 6
-x = 0
x = 0
