So here's the question or a picture
5*2x is 10x
5*3y is 15y
5*5z is 25z
I do not believe so but dont quote me on it.
Answer:
The answer is 10
Step-by-step explanation: You multiply the 2 times twenty to get 40 then multiply the 2 times 2x to get 4x then subtract fourty from both sides and you will get fourty and then divide so 40 divided by 4x equals 10.
