Solving 2-Step Equations

Front

What is a 2-step equation?

Back

A 2-step equation is an algebraic equation that requires two operations to solve for the variable.

Front

What does it mean to combine like terms?

Back

Combining like terms means to simplify an expression by adding or subtracting terms that have the same variable raised to the same power.

Front

Solve the equation: 20d + 8 - 2 - 10d = ?

Back

10d + 6

Front

Combine like terms and solve: 6x + 4 + 2x = ?

Back

x = 2

Front

Solve the equation: 9 + 3x = 10

Back

x = 1/3

Front

What is the first step in solving a 2-step equation?

Back

The first step is to isolate the variable by performing the inverse operation of the constant term.

Front

What is the second step in solving a 2-step equation?

Back

The second step is to perform the inverse operation of the coefficient of the variable.

Front

Solve the equation: 3y - 6 = 12

Back

y = 6

Front

What is the solution to the equation: 5x + 3 = 18?

Back

x = 3

Front

What does it mean to isolate a variable?

Back

Isolating a variable means to manipulate the equation so that the variable is on one side and all other terms are on the opposite side.
