6.EE.B.7 Write and Solve Equations (x + p = q and px = q)

Front

What is an equation?

Back

An equation is a mathematical statement that asserts the equality of two expressions, typically containing one or more variables.

Front

What does the variable 'x' represent in an equation?

Back

The variable 'x' represents an unknown value that we are trying to solve for in an equation.

Front

What is the first step in solving the equation x + 5 = 12?

Back

Subtract 5 from both sides of the equation to isolate x.

Front

What is the solution to the equation 3x = 12?

Back

x = 4, because you divide both sides by 3.

Front

What does the term 'solving for x' mean?

Back

It means finding the value of the variable x that makes the equation true.

Front

What is the ADDITION Property of Equality?

Back

If you add the same number to both sides of an equation, the two sides remain equal.

Front

What is the SUBTRACTION Property of Equality?

Back

If you subtract the same number from both sides of an equation, the two sides remain equal.

Front

How can you represent the statement 'Riley lives 25ft less than PJ' as an equation?

Back

r = p - 25, where r is Riley's distance and p is PJ's distance.

Front

What is a variable in mathematics?

Back

A variable is a symbol, often a letter, that represents an unknown value in an equation.

Front

What is the solution to the equation v + 4 = 11?

Back

v = 7, because you subtract 4 from both sides.
