• X = 8

What is a variable in an equation?

• A variable is a constant value that does not change.

• A variable is a symbol, often represented by a letter, that stands for an unknown value.

• A variable is a type of equation that has no solution.

• A variable is a number that is always positive.

What does it mean to isolate the variable in an equation?

• To combine like terms on both sides of the equation.

• To manipulate the equation so that the variable is on one side and all other terms are on the opposite side.

• To eliminate the variable from the equation entirely.

• To substitute the variable with a numerical value.

What does the 'Golden Rule' refer to in solving equations?

• Performing the same operation on both sides of the equation to maintain equality.

• Using the same numbers in both sides of the equation.

• Adding the same value to both sides of the equation only when necessary.

• Multiplying both sides of the equation by the same number to simplify.

What is the first step to check your solution?

• Substitute the variable with the answer in the original equation.

• Rewrite the equation in a different form.

• Check the solution against a different problem.

• Graph the equation to visualize the solution.

What is the opposite operation of multiplication?

• Addition

• Subtraction

• Division

• Exponentiation

If you have the equation 2z = 16, what is z?

• z = 4

• z = 6

• z = 8

• z = 10

What are inverse operations?

• Pairs of operations that undo each other, such as addition and subtraction or multiplication and division.

• Operations that are always performed in the same order.

• Operations that cannot be reversed once completed.

• Operations that yield the same result regardless of the order.

Solve the equation: 1 + a = 15

• a = 12

• a = 14

• a = 16

• a = 10

What is a one-step equation?

• A one-step equation is an algebraic equation that can be solved in a single step by performing an inverse operation to isolate the variable.

• A one-step equation requires multiple steps to solve for the variable.

• A one-step equation is a type of equation that has no variables.

• A one-step equation can only be solved using graphical methods.
