Step-by-step explanation:
<u>Reading rate is y pages per x minutes and proportional relationship formula is:</u>
<u>The coefficient is:</u>
<u>Let's verify if the given numbers fit into the same relationship:</u>
- 12/18 = 2/3
- 8/12 = 2/3
- 20/30 = 2/3
We confirm all same and it means k = 2/3
<u>Required equation is:</u>
This represents that Michael reads 2 pages per 3 minutes and for x minutes he reads 2/3x pages
Answer:

Step-by-step explanation:
x-7y = -49
i) move x to the right-hand side and change its sign
-7y = -49-x
ii) change the signs on both sides of the equation
7y = 49+x
iii) divide both sides of the equation by 7


iv) use the commutative property to reorder the terms
* commutative property: a+b = b+a
