slope intercept form: y = mx + b
Note the equal sign. what you do to one side, you do to the other. First, subtract 4x from both sides
4x - 3y = 15
4x (-4x) - 3y = 15 (-4x)
-3y = -4x + 15
Next, divide -3 from both sides to isolate the y.
(-3y)/-3 = (-4x + 15)/-3
y = (4/3)x - 5
y = (4/3)x - 5 is your answer
hope this helps
i do not understand what you are asking help for?
Explanation:
So, I know a lot of people won't do it this way, but this is how I would do it.
First, multiply each expense by eight (eight for the eight days)
$55 x 8 = 440
$25 x 8 = 200
$129 x 8 = 1032
Next, take the three answers and add them together:
440 + 200 + 1032 = 1672
Lastly, divide 1672 by four (four for the four friends)
1672/4 = 418
There you go! Here is your answer. Each friend paid $418
Hope I helped! :D
