Which ordered pair is the solution to the system of equations?
-5x-3y=12
x-3y=-6
a.
(3, −3)

b.
(−3, 1)

c.
(6, 4)

d.
(9, 5)

-5x-3y=12

x-3y=-6

Solve x-3y=-6 for x

Add 3y to both sides

x-3y+3y=-6+3y

x= 3y-6

Substitute 3y-6 for x in -5x-3y=12

-5x-3y=12

-5(3y-6)-3y=12

Simplify both sides of the equation

-18y+30=12

Add -30 to both sides

-18y+30+-30=12+-30

-18y=-18

Divide both sides by -18

-18y/-18= -18/-18

y=1

Substitute 1 for y in x = 3y-6

x= 3y-6

x= (3)(1)-6

Simplify both sides of the equation

x= -3

Answer : B

                ( -3 , 1 )

I hope that's really help you Kris ! Have a great night .

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

answer: the answer is one

step-by-step explanation:

pemdas, in this situation there is no parenthesis or exponents so you go to multiplication, 1x1=1, then division 1/1= 1 then addition 1+1=2 then subtraction 2-1=1
