Grade 7 Linear Equations

What we verified before publishing

Fact-check status: passed

The following claims were verified through Perplexity Sonar before the questions were finalised. The host can reference any of them during play:

• A linear equation is an algebraic statement that shows two expressions are equal and contains a variable with an exponent of exactly 1.
• The equal sign in an equation acts like the pivot point of a balanced scale, meaning whatever is done to one side must be done to the other.
• In Grade 7, students solve linear equations of the form x + a = b and ax = b where a and b are integers or whole numbers.
• A key difference between an expression and an equation is that an equation contains an equal sign while an expression is a combination of terms without one.
• The variable in a linear equation represents an unknown quantity that can be a whole number, fraction, or decimal.
• Grade 7 learners solve two-step linear equations of the form px + q = r and p(x + q) = r where p, q, and r are rational numbers.
• The most common example of a linear equation in one variable is a simple balance problem like 3x + 2 = 14.
• To solve a linear equation, you must isolate the variable by reversing the operations using inverse operations like subtraction for addition.
• Preservation of equality is the rule that states if you add, subtract, multiply, or divide one side of an equation, you must do the same to the other side.
• Linear equations in Grade 7 are used to solve real-life problems involving money, measurements, and rates by representing quantities with variables.
