Answer:
So, the relation between variables are

Step-by-step explanation:
We are given

Since, we have to find relation between variables
so, we can solve for y

Firstly, we will multiply both sides by y

we can simplify it

we can isolate y
so, we can divide both sides by 7
so, we get

Answer:

Step-by-step explanation:
Let
x ----> the length of Zach's car
y ----> the length of Ginny's car
we know that
The sum of the lengths of both cars is 30 inches
so
----> equation A
Ginny's car is 2 more than 3 times the length of Zach's car
so
----> equation B
substitute equation B in equation A

Answer:
put 8/3
Step-by-step explanation:
Given

You have to plug in a random y value and use algebra to solve for x. It is impossible to do without at least one point for y.
