We substitute the given into the equation
given: a=-1, b=2, c=

=(

-1
=

-1

-1
=

-1
to continue, we can either find a common denominator or change the fraction to decimal.
Fraction to Decimal:

=-2.5
Equation=-2.5-1=-3.5
OR Common Denominator:
=


×

(denominator should be -2=common)
=

+

=

which also = to -3.5

Answer:</h3>
<em>Your answer would be y=x+3/12</em>
<h3>
Step-by-step explanation:</h3>
Firstly, you'll switch sides of the equation.
<em>y=12x+3 ---> x=12y-3</em>
Next, add 3 to both sides.
<em>x=12y-3 ---> 12y-3+3=x+3</em>
Simplify it.
<em>12y-3+3=x+3 ---> 12y=x+3</em>
Then, divide both sides by 12.
<em>12y=x+3 ---> 12y/12 = x/12 + 3/12</em>
Simplify once more.
12y/12 = x/12 + 3/12 --- y= x+3/12
<u>y=x+3/12 would be your answer.</u>

I really don't know, what the answer is...
But, I think it is....
