Answer:
1. x+y=16 (the y’s cancel because they are inverse operation)
x-y=10 (x+x=2x and 16+10=26 now the equation is 2x=26 now just solve for x by dividing 2 on both sides 26/2=13)
YOUR NOT DONE YET: (Now that we've found x let's plug it back in to solve for y.Write down an original equation I’m using x+y=16 And Substitute 13 for x)
the equation is 13+y=16 now subtract 13 on both sides and you should get y=3
2. for number 2 it’s the same as number 1
3. in this one the x will cancel each other because they are inverse)
(for the rest please use the website: Mathpapa it’s very helpful I would do more but I’m running out of time hopefully you can use this as a example to do the rest I’m really sorry I couldn’t do the rest)
