Answer:
An equation is basically a way to show a relationship of variables (x,y,a,b, etc) and numbers. The relationship between these numbers and variables is a lot like a laundry bag. If you are given a laundry bag that only has your pants in it, you could call this laundry bag "x". Then you have your other laundry bag which only has your shirts in it, this could be called laundry bag "y". The amount of shirts and pants in each of those laundry bags could be counted separately, or if you combine them, counted together.
Step-by-step explanation:
This could be shown like:
total amount of clothes.
If you have 5 shirts which equals y, and 2 pants which equals x, you could quickly count how many clothes in total you have.
Total amount of clothes
Place x=2 and y=5 into that equation.
Which gives you your total clothes.
