Question

Could someone please help me?

Answer 1

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.

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

Answer 3

y=-4 and x=

Answer 4

I dont understand??

Answer 5

THIS is more of an example of how to do it
The answer is probably wrong.

-3x+7y=-16
+3x +3x
7y=-16+3x
/7
y=2.28+3x


-9x+5(2.28+3x)=16

-9x+11.4+15x=16
2.4x=16
/2.4
x=6.7

y=2.28+3(6.7)
y=2.28+20.1
y=22.38

Y=22.38
X=6.7

Answer 6

How would I be able to combine them though?
