Answer:

Step-by-step explanation:
You want to isolate r. As you can see all the numbers on the right would be multiplied so to isolate r you would have to divide the numbers on the right and do the same to the left side.
whattt Step-by-step explanation:
Multiplication property of equality can be used to solve: 
Step-by-step explanation:
First of all, lets define the multiplication property of equality
The multiplication property of equality states that if one side of an equation is multiplied with any number the other side is also multiplied with the number.
Given equations are:

By observing the equations we can see that only third equation has a fraction in it so it has to be multiplied with -2 for solution

Hence,
Multiplication property of equality can be used to solve:

The ordered pairs of the points F, G and H are their locations on the coordinate plane
The point F is above the line 1
<h3>How to determine the coordinate point?</h3>
The ordered pairs of the points are given as:
F = (0,7)
G = (6, 2)
H = (1,6)
The line is not given; so, I will provide a general explanation.
Of all the three ordered pairs, the point with the greatest y-coordinate is the point F.
This means that the point F can be above the line 1, while the other points G and H are below the line.
See attachment for the illustration of the line and the ordered pairs
