Key Concepts
New Concept An equation is a statement which indicates that two expressions are equal.
Why it matters Equations are the language used to describe relationships in everything from physics to finance. Mastering the properties of equality is your first step toward building complex models and solving for unknown variables in any system.
What’s next Next, you’ll apply the properties of equality to solve equations with variables on one or both sides, and even those involving fractions.
Common Questions
How do you solve a linear equation in Grade 10 algebra?
Treat the equation like a balanced scale. Use inverse operations to isolate the variable. For m + 7 = 19: subtract 7 from both sides to get m = 12. Whatever you do to one side, do to the other.
What are inverse operations in equation solving?
Inverse operations undo each other: addition undoes subtraction, multiplication undoes division. To isolate a variable being added to by 7, subtract 7 from both sides.
Why must you perform the same operation on both sides?
The equals sign means both sides are balanced. If you only change one side, the equation becomes false. Always apply the same operation to both sides to maintain the balance.
