Simplifying Expressions and One/Two Step Equations Review

Front

What is the process of simplifying an expression by combining like terms?

Back

Combining like terms involves adding or subtracting terms that have the same variable raised to the same power. For example, in the expression 3x + 4x, you can combine the like terms to get 7x.

What is a one-step equation?

Back

A one-step equation is an equation that can be solved in a single step, typically by performing the inverse operation. For example, in the equation x + 5 = 10, you can solve for x by subtracting 5 from both sides.

Solve for x: 9x - 2 = 79

Back

x = 9

Front

What is a two-step equation?

Back

A two-step equation requires two operations to solve for the variable. For example, in the equation 2x + 3 = 11, you first subtract 3 and then divide by 2.

Simplify the expression: 9x^2 + 14x - x^2 + 6x

Back

8x^2 + 20x

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side by itself. This is often done using inverse operations.

Simplify the expression: 8(2x + 3) - 13

Back

16x + 11

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac. It allows you to multiply a single term by each term inside a parenthesis.
