here's the problem:5x+5y=5

7x+7y=14 now my question is do you multiply -7 and 5 to both equations.

Thank you for the opportunity to help you with your question!

Yes you can multiply the first equation by -7 and the second equation by 5.

(5x+5y=5)*-7=-35x-35y=-35

(7x+7y=14)*5=35x+35y=35

Add both right sides of these equations together and you get...

(-35x+35x)+(-35y+35y)=(-35+35)

0x+0y=0

0+0=0

0=0 which is true.

Therefore the answer is that all values of x and y are solutions to this system of equations.

hey for this systems of equations problem 7x+7y=7, 4x+4y=4, I got 0=0 but I wasn't sure if that was right. Can you check it for me.

It is right. 0=0 is a true statement. So all values of x and y are solutions.

thank
