Front

What is a one-step equation?

Back

An equation that can be solved in one operation, such as addition, subtraction, multiplication, or division.

Front

What is a two-step equation?

Back

An equation that requires two operations to solve for the variable.

Front

How do you isolate a variable in an equation?

Back

By performing inverse operations to both sides of the equation.

Front

What is the first step to solve the equation: 9x = 153?

Back

Divide both sides by 9.

Front

What does it mean to 'reduce' an equation?

Back

To simplify the equation by performing operations that make it easier to solve.

Front

What is the solution to the equation: 2x = 10?

Back

x = 5.

Front

How do you check if your solution is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

What is the purpose of using inverse operations in solving equations?

Back

To undo the operations applied to the variable and isolate it.

Front

What is the equation represented by: '400 reduced by twice my age is 260'?

Back

400 - 2a = 260.

Front
