A system of equations is shown below:
-3x + 7y = -16
-9x + 5y = 16
Part A: Create an equivalent system of equations by replacing one equation with the sum of that equation and a multiple of the other. Show the steps to do this. (6 points)
Part B: Show that the equivalent system has the same solution as the original system of equations. (4 points)

To create a new system of equation with the conditions given, let's take for example the first equation:
And let's forget about the "=" sign and center on the following expression:
So I will add to it the second equation, multiplied by any number... let's say... 10...
So, doing some simple algebra:
Ending up with:
And for the second part you'll have to solve the new system of equation formed by the new equation:
