Answer:
Step-by-step explanation:
Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3
Pls mark me brainliest
120% that would be the percentage of 12/10.
12 divided by 10 = 1.2
1.2 times 100 = 120
That is equal to 120%

Answer:
x=16, y=-4
Step-by-step explanation:
-1(x-y=12)

-x+y=-12
x+7y=-20
8y=-32
y=-4
x-4=12
x=16
