James had $15,345.21 withheld from his income one year. He
realized that he only owed $12,971.98 for taxes for the year.

How much will his tax refund be?

$2,373.23

Step-by-step explanation:

-Tax refund is determined by comparing your total income tax to the amount that was withheld for federal income tax.

-Assuming that the amount withheld for federal income tax was greater than your income tax for the year, you will receive a refund for the difference.

#Refund =Withheld -Actual Tax liability=$15345.21-$12971.98=$2,373.23

Hence James' tax refund will be $2,373.23

Step-by-step explanation:

As you can observe in the image attached, the graphed system has a unique solution.

Remember that a system can have one solution, infinite many solutions or none. Where the lines intersect, they would do it in one point only, because they are straight line, in that case we say that the system has a unique solution.

Additionally, where the system is about two parallel lines one on top of the other, we say that the system has infinite many solutions. And, where the lines are parallel each other and not on top, we say the system doesn't have a solution.

Therefore, the right answer is one.
