The first step was the combine the like terms; in this example he is subtracting the 3x on both sides of the =.
If you were to solve the equation it would look like this:
2x+6=3x-8
-3x -3x
-x+6=-8
-6 -6
-x=-14
/-1 /-1
x=14
Standard form is y=mx+b slope m is

and the y-intercept, b, is seen by point P to be -4. So
y=x-4
Answer:
y =.6x+2
Step-by-step explanation:
4 dozen out of the 20 dozen didn't arrive. 4/20 = 1/5 = 20%
