Lesson details
Key learning points
- Starting from a single value for a variable you can write equations that are equivalent.
- A solution to a linear equation is a value that makes the two sides equal .
- All the equivalent equations will have the same solution.
Keywords
Solution - A solution to an equality with one variable is a value which, when substituted, maintains the equality between the expressions.
Equation - An equation is used to show two expressions that are equal to each other.
Common misconception
Pupils may think a value has to be added to each term in an expression.
When adding a term to an expression we can write it as a single addition and then collect like terms if necessary. Show with numbers first
