What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step, typically involving addition, subtraction, multiplication, or division.

Front

How do you solve the equation x + 12 = 20?

Back

Subtract 12 from both sides: x = 20 - 12, so x = 8.

Front

Back

It represents that three times the number of fish caught last year (f) equals 63 fish caught this year.

Front

How do you isolate a variable in an equation?

Back

To isolate a variable, perform the inverse operation on both sides of the equation.

Front

What is the solution to the equation y - 33 = 147?

Back

Add 33 to both sides: y = 147 + 33, so y = 180.

Front

What does '5 less than a number' mean in algebra?

Back

It means to subtract 5 from that number, represented as x - 5.

Front

How do you solve the equation 42 = 7f?

Back

Divide both sides by 7: f = 42 / 7, so f = 6.

Front

What is the first step to solve the equation x - 5 = 15?

Back

Add 5 to both sides: x = 15 + 5, so x = 20.

Front

What is an algebraic expression?

Back

An algebraic expression is a combination of numbers, variables, and operations without an equality sign.

Front

What is the purpose of using variables in equations?
