Does x satisfy the equation?

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 it mean for a value to satisfy an equation?

Back

A value satisfies an equation if, when substituted for the variable, it makes the equation true.

Front

How do you solve a simple linear equation?

Back

To solve a simple linear equation, isolate the variable on one side of the equation using inverse operations.

Front

What is the solution of the equation x - 6 = 6?

Back

The solution is x = 12.

Front

How do you check if a value is a solution to an equation?

Back

Substitute the value into the equation and see if both sides are equal.

Front

What is the solution of the equation 3a = 18 when a = 6?

Back

Yes, because substituting 6 gives 3(6) = 18, which is true.

Front

What is the solution of the equation 26 = y - 9 when y = 35?

Back

Yes, because substituting 35 gives 26 = 35 - 9, which is true.

Front

What is the solution of the equation x + 15 = 10 when x = -5?

Back

Yes, because substituting -5 gives -5 + 15 = 10, which is true.

Front

If m = 19, what is the solution of the equation m - 4 = 15?

Back

True, because substituting 19 gives 19 - 4 = 15, which is true.
