Write and Solve One-Step Equations/Ineq.

Front

What is a one-step equation?

Back

A one-step equation is an algebraic equation that can be solved in a single step by performing the same operation on both sides of the equation.

Front

How do you solve the equation y + 12 = -15?

Back

Subtract 12 from both sides: y = -15 - 12, so y = -27.

Front

What does the equation 3f = 63 represent?

Back

It represents that Todd caught three times as many fish this year than last year, and he caught 63 fish this year.

Front

How do you find the value of n in the equation n + 30 = 47?

Back

Subtract 30 from both sides: n = 47 - 30, so n = 17.

Front

What is the solution to the equation 12x = 600?

Back

Divide both sides by 12: x = 600 / 12, so x = 50.

Front

How do you solve the equation 16 = m/8?

Back

Multiply both sides by 8: m = 16 * 8, so m = 128.

Front

What is an inequality?

Back

An inequality is a mathematical statement that compares two expressions and shows that one is greater than, less than, or not equal to the other.

Front

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

Back

To isolate a variable means to manipulate the equation so that the variable is on one side by itself.

Front

What is the first step in solving the equation y + 12 = -15?

Back

The first step is to subtract 12 from both sides of the equation.

Front

What is the solution to the equation 3f = 63?

Back

Divide both sides by 3: f = 63 / 3, so f = 21.
