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

Identify the equation: 6x + 5 - 8x - 1, 5(x + 4) = 3x, x + 7 > 13, πr² + πrh

Back

5(x + 4) = 3x

Front

What is the solution to the equation: y + 4.6 = 12?

Back

Back

No

Front

Determine if t = 4 is a solution to the equation: 2t + 5 = 15.

Back

No

Front

What is the first step to solve the equation: 2x + 3 = 11?

Back

Front

If an equation is true for a certain value of the variable, what is that value called?

Back

solution

Front

What is the process of checking if a value is a solution to an equation?

Back

Substituting the value into the equation and verifying if both sides are equal.

Front

What does it mean if an equation has no solution?

Back

It means there is no value for the variable that can make the equation true.
