Answer:

x=7/15

Step-by-step explanation:

I'm not sure what x means but if you solve the equation it is 7/15

First you would set 10x+15 equal to 25x+8 which would look like 10x+15=25x+8

Then you would combine like terms by subtracting 8 from both sides to get 10x+7=25x

Then subtract 10x from both sides and get 7=15x

So then to get x by itself you would divide both sides by 15 and get 7/15=x

Answer:

4x=y

Step-by-step explanation:

4x=y is your answer because if x is 5, like in the table, then 4(5) would equal 20, which is the y-value. It also works for every number in the table.
