Rewriting Literal Equations

Front

What is a literal equation?

Back

A literal equation is an equation that contains two or more variables. It is often used to express a relationship between different quantities.

Front

How do you isolate a variable in a literal equation?

Back

To isolate a variable, you need to perform inverse operations to get the variable on one side of the equation by itself.

Front

What is the first step in rewriting the equation 2x + 3 = 7 to solve for x?

Back

Subtract 3 from both sides of the equation to get 2x = 4.

Front

What is the solution for x in the equation 2x = 4?

Back

Divide both sides by 2 to find x = 2.

Front

What does it mean to 'rewrite' an equation?

Back

To 'rewrite' an equation means to express it in a different form, often to isolate a specific variable.

Front

In the equation y = 3x + 5, how can you rewrite it to solve for x?

Back

Subtract 5 from both sides to get y - 5 = 3x, then divide by 3 to get x = (y - 5)/3.

Front

What is the purpose of rewriting equations?

Back

Rewriting equations helps to solve for a specific variable, making it easier to understand relationships between variables.

Front

How do you rewrite the equation A = lw to solve for l?

Back

Divide both sides by w to get l = A/w.

Front

What is the relationship between variables in the equation C = 2πr?

Back

C represents the circumference of a circle, r is the radius, and π is a constant. This equation shows how circumference depends on radius.

Front

What is the process to rewrite the equation 4y - 2 = 10 to solve for y?

Back

Add 2 to both sides to get 4y = 12, then divide by 4 to find y = 3.
