What is a word problem I could use for 4 x -2?

John and Smith are having some money given by their mothers for shopping . John have two less than four times money of Smith . The sum of money John & Smith have is $20 . Find how much money does John & Smith have initially given by their mothers ?

Step-by-step explanation:

Basically a word problem is an exercise where significant background information on the problem is presented as text rather than in mathematical notation. Word problem are mostly the practical scenarios in life which are in form of text & we convert them in form of mathematical equations!

An example of a simple word problem is : Jane has $5.00, but uses $2.00 to buy something. How much money does she have now? Now , in question we need to design a word problem where we can use 4x-2 !

We can think of an example as : John and Smith are having some money given by their mothers for shopping . John have two less than four times money of Smith . The sum of money John & Smith have is $20 . Find how much money does John & Smith have initially given by their mothers ?

answer: -2+√x,-2-√x

i hope this , i don't know if you're looking for a pair or not.
