Question

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)

Answer 6

Part A: I replace 2nd equation with sum of 1st and 2nd equation so I get system:
-3x + 7y = -16
-12x + 12y = 0

Answer 7

Part B - You must solve original system of equation; you will get solution:
x = -4
y = -4

And then substitute this solution into equivalent system of equation:
-3*(-4) + 7*(-4) = -16
-12*(-4) + 12*(-4) = 0
And evaluate expressions to prove that equivalent system of equation have same solution.

Answer 8

OMFG TY TY TY TY

Answer 9

is this the final answer for B? @triangleguru ?

Answer 10

B - I think thats final solution. In A part I constructed replaced equation sa B = 1*A+B. So multiple coeficient was "1". If you choose B = 2*A+B, you will get equivalent system:

-3x + 7y = -16
-15x + 19y = -16
