Solving one step addition and subtraction equations

What is the first step in solving a one-step subtraction equation?

• Isolate the variable by performing the opposite operation.

• Add the same number to both sides of the equation.

• Multiply both sides by the coefficient of the variable.

• Divide both sides by the constant term.

Why is it important to understand equations?

• It is essential for memorizing historical dates.

• Understanding equations helps in solving real-world problems and developing critical thinking skills.

• It is only useful for advanced mathematics courses.

• It has no practical application in daily life.

What is a variable in mathematics?

• A symbol that represents a known number in an equation.

• A constant value that does not change.

• A symbol, often a letter, that represents an unknown number in an equation.

• A type of mathematical operation.

What is an equation?

• A mathematical statement that shows that two expressions are equal, often containing a variable.

• A type of graph that represents data visually.

• A formula used to calculate the area of a shape.

• A number that represents a quantity.

What is the opposite operation of subtraction?

• Multiplication

• Division

• Addition

• Exponentiation

Solve: c - 4 = 4

• c = 6

• c = 7

• c = 8

• c = 9

Is 5 a solution for w - 6 = 1?

• Yes, because substituting 5 gives 1.

• No, because substituting 5 gives -1, not 1.

• Yes, because 5 is greater than 1.

• No, because 5 is less than 1.

Solve: y + 0 = 2

• y = 1

• y = 2

• y = 3

• y = 0

What is the first step in solving a one-step addition equation?

• Isolate the variable by performing the opposite operation.

• Add the same number to both sides of the equation.

• Multiply both sides of the equation by the same number.

• Subtract the variable from both sides of the equation.

What is a one-step equation?

• A type of equation that requires multiple operations to solve.

• An equation that can be solved in a single operation.

• An equation that has no solution.

• An equation that involves fractions and decimals.
