Linear Equations · Grades 7–8
Linear Equations Worksheets
Linear equation worksheets from one-step problems through variables on both sides. Treat it as a balance scale, do the same to each side, and the method never really changes.

What it is
A linear equation is a balance: whatever you do to one side you must do to the other to keep it equal while you isolate the variable.
Why it matters
Every method for solving a linear equation comes down to the same idea, keep both sides equal while isolating the variable, and that one idea is what every later algebra course assumes a student already has automatic.
How to do it
- Simplify each side, then collect the variable terms on one side.
- Undo addition or subtraction first, then undo multiplication or division.
- State the value of x and check it in the original equation.
Examples by level
- Beginner2x = 2Answerx = 1
- Intermediate8x − 4 = 4x − 12Answerx = -2
- Advanced10x − 8 = 11x + 4Answerx = -12
Examples are generated by the same engine as the worksheets, so they're always mathematically correct. Built to avoid repeats, not reshuffle the same handful of questions.
Common mistakes
- Doing an operation to only one side of the equation.
- Sign errors when moving terms across the equals sign.
- Dividing before undoing addition or subtraction.
Tips
- Always do the same operation to both sides.
- Check your answer by substituting it back into the equation.
For parents
Treat the equation as a balance scale, whatever you do to one side, do to the other.
For teachers
Insist students verify each solution by substitution; it catches sign errors and builds confidence.
Key vocabulary
- variable
- an unknown value, often written x
- coefficient
- the number multiplying the variable
Frequently asked questions
- How do you solve a two-step equation?
- Undo addition or subtraction first, then undo multiplication or division, keeping both sides balanced.
- What is a variable?
- A variable is a letter that stands for an unknown number you're solving for, most often x.
