Substitution doesn't work for this, but elimination does.
-6x-8y=-20 +6( x+6y=-6)
-6x-8y=-20 + 6x+36y=-36
-6x and 6x cancel each other, add -8 and 36 to get 28, and -20 and -36 to get -56.
28y=-56
divide by 28 on both sides.
Y= -2
Then substitute y into one of the equations.
x+6(-2)=-6
x-12=-6
x=6
The ordered pair is (6,-2).
To find them it's y=mx+b
b=the y intercept
m=the slope

Answer:
This is guess of what the question is asking:
I had got 49x - 21y - 6.
Step-by-step explanation:
7 x 7 is 49 and 7 x 3 is 21.
You have to distribute the 2/3 across the equation.
8/3x+18/3 which is 8/3x+6 so the answer is a
