What is the first step in solving the equation 4x + 9 = -2x - 15?

Back

The first step is to add 2x to both sides to combine like terms.

Front

Solve for x: 4x + 9 = -2x - 15

Back

x = -4

Front

What does it mean to combine like terms?

Back

Combining like terms means to add or subtract terms that have the same variable raised to the same power.

Front

What is the solution to the equation 2x - 1 = 3x + 8?

Back

x = -9

Front

How do you check if your solution to an equation is correct?

Back

Substitute the solution back into the original equation to see if both sides are equal.

Front

Solve for x: 4 = 2(x + 3)

Back

x = -1

Front

What is the distributive property?

Back

The distributive property states that a(b + c) = ab + ac, allowing you to multiply a single term by two or more terms inside a parenthesis.
