7th 5-2 Solve 2 Step Equations

Front

What is a two-step equation?

Back

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

Front

What is the first step to solve the equation: -5x - 8.4 = 17?

Back

Add 8.4 to both sides.

Front

What is the first step to solve the equation: 11 - 3x = 44?

Back

Subtract 11 from both sides.

Front

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

Back

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

Front

What operation would you perform to both sides of the equation to eliminate a constant term?

Back

You would add or subtract the constant term from both sides.

Front

What is the solution to the equation: 2x + 4 = 12?

Back

x = 4.

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

What is the purpose of using inverse operations in solving equations?

Back

Inverse operations are used to undo the operations applied to the variable, helping to isolate it.

Front

What is the first step to solve the equation: 3x + 5 = 20?

Back

Subtract 5 from both sides.

Front

What is the solution to the equation: 4x - 8 = 0?

Back

x = 2.
