What is a proportion?

Back

A proportion is an equation that states that two ratios are equal.

Front

How do you solve the equation 5x + 7 = 12?

Back

Subtract 7 from both sides to isolate the term with x: 5x = 5, then divide by 5 to find x = 1.

Front

What is the first step in solving the equation 3y - 2 = -29?

Back

Add 2 to both sides to isolate the term with y: 3y = -27, then divide by 3 to find y = -9.

Front

How do you determine if two ratios form a proportion?

Back

Cross-multiply the ratios and check if the products are equal.

Front

What is the solution to the equation 3(x - 2) = 18?

Back

Add 6 to both sides to get 3x = 24, then divide by 3 to find x = 8.

Front

What does it mean to solve for x in an equation?

Back

To find the value of x that makes the equation true.
