    B.An expression is something that can bee simplified
    C.Any and all value of the variable that satisfies an equation, inequality, system of equations, or system of inequalities.

  2. An equation is like a maths sentence, like 4x=16. An expression is a maths sentence that cannot be solved, like 5x=2y+1. A solution is the way to answer the question most efficiently.

  5. A. An equation's Left Hand Side and Right Hand Side are both equal, for example: 2x + 11 = 13 , equations are able to be solved.

    B. An expression can only be simplified or factorised, but not solved fully, such as: 2x + 11 .

    C. A solution is the answer to the expression, like the 1st example, 11 is the solution.

  6. A. An equation is a mathematical sentence built from expressions using one or more equal signs (=).

    B. Expressions may not contain the equal sign (=) or any type of inequality signs such as (≤), (≤) or (≠).

    C. A solution is an algebraic term that satisfies an expression or equation

  7. An equation is a mathematical sentence where both sides of the = sign are equal.
    An expression is a combination of symbols and numbers, or just symbols that can be simplified.
    An equation is the answer to a question.
