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)

Best ResponseYou've already chosen the best response.2To create a new system of equation with the conditions given, let's take for example the first equation: \[3x+7y=16\] And let's forget about the "=" sign and center on the following expression: \[3x+7y+16\] So I will add to it the second equation, multiplied by any number... let's say... 10... \[(3x+7y+16)+(10)(9x+5y16)\] So, doing some simple algebra: \[(3x+7y+16)90x+50y160\] Ending up with: \[93x+57y144\] And for the second part you'll have to solve the new system of equation formed by the new equation: \[93x+57y=144\] \[9x+5y=16\]
