Biology
you are correct

x-2y=-1 -x+5y=4 x=-1 y=1

Use the numbers 1,2,3,4,5, and 6 to write a subtraction problem with 2 mixed numbers that have a difference of 4 13/20.

Explain how you know whether to add a number to or subtract a number from both sides of an equation in order to solve the equation.

How can you draw a line that is 5 inches long using only one sheet of 8 1/2 in X 11 in notebook paper?

Thanks for your help with the solving of the three equations! Yes, it was a typo. I just finished solving it a long way, solving for the 1st 2 equations then the 2nd and 3rd and plugging in variables...etc. etc. Your way gave the same answer, but quicker, does your way always ...

Thanks, yes, typo I just finished solving it a long way, I solved the first two, then the second two,,etc etc. Your way seems much easier, I did get the same answers, yeah!!!! But, will your way always work?
