Coefficients are y and x
Variables are the number with the letters
The terms are the numbers
First, we subtract 12x from both sides. We then get -4y=-12x+48. We then divide this by -4 on both sides to get the y by itself. We then get that the equation is y=3x-12.
Answer: its AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
Answer: Josh = 19.8 hours, Danny = 10.8 hours
<u>Step-by-step explanation:</u>


Since time cannot be negative, x=-5.8 is an extraneous solution (not valid) so x = 10.8
Josh: x + 9 --> 10.8 + 9 = 19.8
Danny: x --> 10.8
****************************************************************************************
2a) k = 9.45 & 0.55
2b) x = 3/2
2c) x = 2/3 <em>(x = -1 is an extraneous solution so is not valid)</em>
2d) No Solution <em>(x = 1 is an extraneous solution so is not valid)</em>
Here is the work for 2a. Follow this format for b, c, & d
