Write Equations With a Given Number of Solutions
Written by Adi Ackerman, Head Teacher
"Write Equations With a Given Number of Solutions" is written for 8th Grade (Ages 13-14), and it covers Common Core 8.EE.C.7.A. A 7th grader who is already steady on algebra can use it too, and an older student can use it as a short review.
8th grade math worksheet: fill each box so an equation has one, no or infinitely many solutions, then give a reason. Answer key included. Part of our number of solutions algebra collection. Aligned to Common Core standards.
How do I use this worksheet?
Use the test values sheet first so students see what a solution is. Then classify, build and sort. The card sort works well with partners.
What students will practice
- Students will choose numbers that give an equation a set number of solutions.
- Students will build equations such as 4(x + 2) = 4x + 8 with infinitely many solutions.
- Students will write a reason for each of the 9 choices.

Expressions and Equations · 8th Grade
Standard: Give examples of linear equations in one variable with one solution, infinitely many solutions, or no solutions. Show which of these possibilities is the case by successively transforming the given equation into simpler forms, until an equivalent equation of the form x = a, a = a, or a = b results (where a and b are different numbers).

FAQ
How do I use this number of solutions worksheet?
⌄
Use the test values sheet first so students see what a solution is. Then classify, build and sort. The card sort works well with partners.
What does this worksheet teach?
⌄
Fill each box so an equation has one, no or infinitely many solutions, then give a reason. The directions on the page read: Fill each box so the equation has the solutions shown. Give a reason. An answer key is included.
Can I use this number of solutions worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 8th grade algebra, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
How do you know if an equation has no solution?
⌄
Simplify both sides. If the x terms cancel and a false statement is left, such as 5x + 3 = 5x − 7 turning into 3 = −7, no value of x works. The equation has no solution.
When does an equation have infinitely many solutions?
⌄
When both sides simplify to the same expression, such as 2(x + 4) = 2x + 8. Every value of x makes it true. The x terms cancel and a true statement like 8 = 8 is left.
How do you check if a value is a solution?
⌄
Substitute the value into each side and find the left and right values. If they are equal, it is a solution. Is It a Solution? Test Values in Equations has 12 equations, some with fraction values such as 5/2.
