Medals. Can someone walk me through how to do this?

A system of equations is shown below:

8x + 5y = 9
3x + 2y = 4

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.

Part B: Show that the equivalent system has the same solution as the original system of equations.

8x + 5y = 9
3x + 2y = 4

To solve for a variable, you need to "eliminate" one. You can do that either by multiplying the first equation by -3 and the second by 8, or by multiplyng the first by -2 and the second by 2. (the negatives/positive can be vice versa)

I'm not exactly sure what the question is asking for, but I do know how to solve this system of equations

is there anything you can tell me about question B? Do you have any guess what its asking?

secret-ninja · Answer

8x + 5y = 9 
3x + 2y = 4

x=-2  y = 5

Multiplying both equations by 2
16x + 10y = 18
6x +4y =8

x = -2  y = 5
