What is the Distributive Property?

Back

The Distributive Property states that a(b + c) = ab + ac, meaning you can distribute a factor across a sum.

How do you solve the equation 2x + 1 = 5x - 3?

Back

Subtract 2x from both sides: 1 = 3x - 3. Then add 3 to both sides: 4 = 3x. Finally, divide by 3: x = 4/3.

Front

What does it mean if an equation has no solution?

Back

An equation has no solution if there are no values for the variable that make the equation true, often resulting in a contradiction.

What is the solution to the equation 3(2x + 1) = 6x + 1?

Back

The equation simplifies to 6x + 3 = 6x + 1, which leads to 3 = 1, a contradiction, indicating no solution.

What is the first step to solve 2 + 14a = -8 + 9a?

Back

Subtract 9a from both sides: 2 + 5a = -8.

Front

What is the solution to the equation 4 - 2(x - 3) = 24?

Back

First, distribute: 4 - 2x + 6 = 24. Combine like terms: 10 - 2x = 24. Then, solve for x: x = -7.

Front

What does it mean if an equation has infinitely many solutions?

Back

It means that any value for the variable will satisfy the equation, often resulting from equivalent expressions.
