The result of making the required variable the subject in both equation are :
- <em>p = w - cg</em>
- <em>h = - (m - r - 4d)</em>
<u>Making p the subject in w = p + cg :</u>
w = p + cg
<em>Subtract cg from bith sides </em>
w - cg = p + cg - cg
p = w - cg
2.)
<u>Make h the subject m = r - h + 4d </u>
m = r - h + 4d
<em>Subtract r from both sides</em>
m - r = r - h + 4d - r
m - r = - h + 4d
<em>Subtract 4d from both sides </em>
m - r - 4d = - h
<em>Divide both sides by - 1</em>
h = - (m - r - 4d)

Answer:
29.25
Step-by-step explanation:
First find the discount
45 *35%
45*.35
15.75
Subtract this from the original price
45-15.75
29.25
Let x = the other rational number.
x(66/7) = (48/5)
Solve for x to find your answer.
5x + 4x = 720
9x = 720 (divide by 9)
X= 80
In order to get the bigger ratio, which is 5, you would substitute x for 80. (I'm bad at explaining)
Work:
5(80)= 400
A Coefficient is the answer
