Given:

There are given the equation:

\begin{gathered} x=-y-6...(1) \\ -7x+6y=-10...(2) \end{gathered}

Explanation:

From the equation (1):

Put the value of x into the equation (2):

So,

From the equation (2):

\begin{gathered} \begin{equation*} -7x+6y=-10 \end{equation*} \\ -7(-y-6)+6y=-10 \\ 7y+42+6y=-10 \\ 13y=-10-42 \\ 13y=-52 \\ y=-4 \end{gathered}

Now,

Put the value of y into the equation (1):

So,

From the first equation:

\begin{gathered} \begin{equation*} x=-y-6 \end{equation*} \\ x=-(-4)-6 \\ x=4-6 \\ x=-2 \end{gathered}

Final answer:

Hence, the ordered pair of the solution is shown below:

(-2,-4)

A ball weighs 15lb on earth and 5.7 pounds on mars. What is the constant proportionality between weight of an object on mars and
krok68 [10]
So its asking you to find the gravity on earth relative to the gravity on mars.

Set up an equation to figure out the difference between the two gravities 

15x=5.7
\\x=5.7/15
x=.38

I don't know what constant of proportionality is in this context but a ball on mars would weigh .38 the amount that it does on earth.
