Question

PLEAZE HELP !!!!!!!
A system of equations is shown below:
5x - 5y = 10
3x - 2y = 2

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 2

I will try to solve your system of equations.
5x−5y=10;3x−2y=2
Step: Solve5x−5y=10for x:
5x−5y+5y=10+5y(Add 5y to both sides)
5x=5y+10
5x
5
=
5y+10
5
(Divide both sides by 5)
x=y+2
Step: Substitutey+2forxin3x−2y=2:
3x−2y=2
3(y+2)−2y=2
y+6=2(Simplify both sides of the equation)
y+6+−6=2+−6(Add -6 to both sides)
y=−4
Step: Substitute−4foryinx=y+2:
x=y+2
x=−4+2
x=−2(Simplify both sides of the equation)
Answer:
x=−2 and y=−4
I hope this helps. (:

Answer 3

Great work @x3mbD4rkSt4rx , you are super-duper fast.

Answer 4

Thanks lol xD. I had this problem awhile ago with helping my sister. So, I had it in my notes on my computer. So anytime!(:

Answer 5

And that's what OpenStudy is. "Learning goes viral, on openstudy".

Answer 6

Indeed it does.

Answer 7

@x3 @2know
However - you r solution is NOT what the question demands

You have solved by substitution but the question explicitly asks for an elimination method

@layla.McCoy Are you still looking at this?

Answer 9

1) Don't post problems with none of YOUR work showing.
2) Certainly don't tag the world unless you FIRST show YOUR work.
