Systems of equations worksheet

Every system here has exactly one solution and it is a whole-number point, because the point is chosen first and the equations are built around it. Tick substitution to get systems where one variable is already alone, or elimination for ones that line up.

Select your difficulty

Pick more than one for a sheet that mixes them.

How to do these

x+3y=92xy=4

  1. The first equation gives x = 9 - 3y.
  2. Put that into the second: 2(9 - 3y) - y = 4.
  3. 18 - 7y = 4, so y = 2, and then x = 3.

The answer is (3,2).

Where students go wrong

Stopping after finding one variable. A system has two answers and they come as a pair, so finding y = 2 is halfway. The other one is not checking: putting the point back into both equations takes ten seconds and catches every arithmetic slip.

Also called simultaneous equations, the addition method, the elimination method or the substitution method.

What you can put on this worksheet

Set up for substitution
x=2y+23x+y=1 (0,1)
Set up for elimination
x3y=34x+3y=3 (0,1)
Is the point a solution
Is (0,1) a solution of the system x3y=2 and 4x4y=2? No, it fails both
One, none or infinitely many solutions
How many solutions: y=3x5 and y=3x+3 No solution

Questions about these worksheets

Yes. Every systems of equations sheet is free to print and free to download as a PDF. There is no account to make, no email to hand over and no limit on how many you take.

Yes. The answer key prints on a second page, and you can choose whether it shows each question beside its answer or just the answers in a list.

Yes. Print straight from the page, or download the PDF and print that. The sheet is laid out for paper rather than squeezed off a screen, so there is room to work under each question, and the answer key comes out on its own page.

Algebra 1 is usually taken around 8th or 9th grade, though schools vary and plenty of students meet it earlier or later. Pick the difficulty rather than the grade: the easy level suits a first lesson on it, the hard level suits review before a test.

Yes, as many as you like. The questions are built fresh each time rather than picked from a fixed set of files, so pressing Generate gives a new sheet. That is what you want for a second class, a retake, or two students sitting next to each other.

That is the closest comparison, and Kuta Software is good software. It is also paid software you install on a computer. These worksheets run in a browser tab for free, with no account and nothing to install. Like Kuta, the systems of equations questions are generated when you ask for them rather than pulled from a fixed set of files, so two classes never get the same sheet, and the answer key comes with it.

Yes. There are three levels, and you can tick more than one for a sheet that mixes them, in which case the questions come out easiest first. The harder levels are not just larger numbers: they ask for something the easy ones do not.

You pick from 4: set up for substitution, set up for elimination, is the point a solution and one, none or infinitely many solutions. Tick as many as you want and set how many of each, or let it spread them evenly.

Stopping after finding one variable. A system has two answers and they come as a pair, so finding y = 2 is halfway. The other one is not checking: putting the point back into both equations takes ten seconds and catches every arithmetic slip.
