<span>x is the total number of liters of orange juice and water combined. 80% of the mixture is pure orange juice which means 20% of it is water. Therefore, x 20/100 = 1 is the equation in single variable that can be used to find x. and 20/100 is 1/5 so there are 5 total liters in all and 5-1 is 4, so there are 4 liters of orange juice in the can. Hope this helps :)</span>
Answer: 5
Step-by-step explanation: Let's go over a little algebra terminology.
The number in front of your variable is called your coefficient and a variable is just a letter that represents any number.
So here, your coefficient is 5 since it appears in front of the variable, x.
