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)

Answer: 3 red marbles, 3 blue marbles, 6 yellow marbles, 8 black marbles, 4 silver marbles

Step-by-step explanation:

I know these are the correct number of marbles because I set up these numbers as fractions and solved for x.

For examples, 2/16 of the marbles are red. 2/16=x/24

You would do this because we are trying to find the number of marbles that are red out of the 24 marbles.

Next, we would do 24 divided by 16= 1.5 Then 1.5 times 2=3

You would follow this rule for each fraction of marbles in order to find the true number of marbles out of 24.
